Class wasn't much better. She tried to hide her pets in her backpack, sincerely hoping and expecting them not to make a noise. But as her teacher was explaining complicated concepts, Simon couldn't help but chime in with his own smarts.

"Hey, guys, would you just knock it off?" asked Meg towards her backpack.

"What the hell was that?" asked her teacher. "Meg, your bag can't be that noisy."

"Oh, I can assure you, it is," said Meg.

"In that case, we'll have to get you tested, because you're clearly going nuts," said her teacher. "Don't worry, we have people to take care of that."

"Um...I think there is something coming out of her backpack," said Neil, trying to edge toward the teacher.

"Oh, now you're going nuts, too?" said her teacher. "Looks like I'll have TWO trips to the psychiatrist's office today!"

"Meg, you probably don't want to talk like that," said Connie. "I know a guy who wore a pink shirt to work, two days later, he was sharing a room with Michael Jackson."

"Michael Jackson?" asked Alvin enthusiastically.

"Well, a guy who claimed to be Michael Jackson."

Suddenly, Clarisse raised her hand.

"You know, maybe we should listen to Meg," she said.

"Oh, great, you heard it too?" said her teacher. "I've got a goddamn funny farm in here!"

"No, I didn't, I just wish we'd listen to Meg after brushing her off," she said. "I'm the new girl here, and she was my first friend. And not because of her brothers."

"Brothers?" asked Meg. "You know about Stewie?"

"I meant those cute little chipmunks in your backpack," she said. "They're your brothers, aren't they?"

"Very funny," said Meg.

"But, you have another brother?"

"Yeah, I do," said Meg. "He's a baby, but acts like a college professor for some reason. A very evil college professor. He could give Benedict Cumberbatch a run for his money!"

"Cool," said Clarisse. "When can I meet your family?"

"Well, assuming my dad doesn't come in and embarrass me, I'll probably invite you over for dinner sometime. Sound good?"

"Hey, Meg, either you've been using all the hot water or peeing in the shower, because apparently, it's not working!" said Peter.

"Dad, how do you even know words like "apparently?"" asked Meg.

"Oh, god," said Meg's teacher. "There's no way in hell this day could get any crazier."

Meg didn't say anything. She just focused on her teacher's lesson, sincerely hoping and expecting that he'd be right. He was teaching a lesson on how quantum physics intertwines with electricity.

"Blah, blah, blah...here are the dynamics for how science intertwines with everyday household appliances...blah blah blah...here's what happens when you turn on a lightswitch...blah blah blah..."

"Electricity?" said a squeaky-toned voice. "Well, well, then-"

Suddenly, Simon jumped out of Meg's backpack and starting singing "Electricity" from SchoolHouse Rock!, using the various tools on his desk, like the lightbulb in the corner, to perform their little skit.

Where do you think it all comes from This powerful... Electricity, Electricity Through high wires to here it comes, They're bringing uh... Electricity, Electricity

Every building must be wired to use it, Uh... Electricity, Electricity

Power plants most all use fire to make it, Uh... Electricity, Electricity

Burnin' fuel and usin' steam, They generate... Electricity, Electricity

Turn that generator by any means, You're making uh... Electricity, Electricity!

"Guys, what the hell?" said Meg. "I'm trying to learn here!"

"Language, Meg!" said her teacher, who had no idea what was happening, and tried to continue his lesson.

"Dude, they're ruining your lesson," said Meg, asking him to turn around.

Meg's teacher couldn't help but look in desperation.

"MEEP" he said.

He was so freaked out, he eventually decided to cancel the rest of the class. Staggering around, he barely had enough energy to get back home, let alone teach anything.

And as for Meg, she didn't even bother telling her parents what happened with Alvin, let alone what happened in class. She was too shocked.

But of course, what should Lois ask first thing when she came home?

"Hey Meg?" she asked. "What happened in school today?"

"Oh, nothing," she lied.

"We joined our new friend in class today!" said Theodore, popping out of her backpack.

"Wait, Meg-" said Lois. "You're meaning to tell me you have-"

"Yes?" said Meg sheepishly.

"-those things in your backpack?" said Lois.

"Oh, these?" asked Meg. "They're...a science project. For school. Yes. I'm studying how the hell science can somehow create chipmunks that can sing."

Cue Lois giving her one of her infamous "you've-got-to-be-kidding-me" looks.

"There's food in the fridge if you're hungry," she said bluntly.

"Yeah, I know," said Meg.

But it was too late. Lois had already left the room, when suddenly, Simon exited her backpack.

"Hey, Meg," he told her. "I didn't realize we were a science project!"

"Yeah, what do you want to study us for, anyway?" asked Alvin.

"Um...well, I," stuttered Meg. "I want to know whatever it is that makes you guys sing, that's all! I mean, it's not every day that you find a bunch of singing chipmunks!"

"She's got a point there," said Simon.

"Whatever," said Alvin. "Just as long as she gives us food, shelter, and a warm space to stay, we'll be alright, okay?"

Oh great, thought Meg to herself. Not only do I have to put up with a bunch of crazy chipmunks, I have to put up with all of their needs. I'll have to feed them, bathe them, tuck them into bed, and probably clean up after them too. Oh god, I'll have to clean up after them. I really wish I had checked my backpack before leaving that place.

She immediately went up to her room to show her new "pets" what they'd have to put up with.

"So here's the bed you guys can sleep in," she told them. "Well, it's technically my bed, but you're my brothers, so you'll have to bunk here."

"Don't you have a bed for real chipmunks?" asked Alvin.

"Shh...Just be glad she's giving us a place to sleep," said Simon.

"And as for food," she told them. "I honestly don't know what you guys like to eat. What the hell is chipmunk food, anyway?"

"Oh, don't worry about us," said Alvin. "We have a surprisingly humanistic diet for a bunch of chipmunks."

"What he means is, our diet consists of mainly human junk food," said Simon. "Especially Theodore's."

"I heard that!" snapped Theodore.

"And about cleaning up after us," said Alvin. "If Theodore does something like drop a raisin, don't worry about that. One of us will eat it."

"Um...eeewwwww?" shrieked Meg.

"Well, it's either this or you're going to have to do this," said Simon. "We don't clean up after ourselves, we're not robots, you know."

"Isn't there something in your bathroom that deals with this kind of stuff?" asked Theodore.

"No, because Dad didn't expect that I'd be adopting a bunch of chipmunks, like, anyday," said Meg.

"Fair enough," said Alvin. "Just be sure to have plenty of nachos on hand, okay?"

"Look, guys, if you really have a hankering for junk food, there's probably a fast food place by the store that sells something," said Meg. "I heard they're opening a new 7-11."

"Meg!" snapped Lois. "What did we say about product placement around your new...whatever the hell you call them!"

"Look, Mom, I'm sorry!" said Meg. "But how else am I supposed to talk to my new friends?"

"Meg, I honestly don't care if you have a bunch of trombone-playing falcons. This is my house, and these are my rules!"

"Told you my life sucked," Meg told the Chipmunks.

"Maybe a little song will cheer you up," said Alvin, jumping up on Meg's plywood desk to perform "Witch Doctor."

All right, you go ooh ee ooh ah ah ting tang walla walla bing bang
All right

Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting tang walla walla bang bang
Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting tang walla walla bang bang
Doh, doh, doh, doh, doh, doh, doh

Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting tang walla walla bang bang
Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting ting walla walla bang bang

Doh, doh, doh, doh
I told the witch doctor, I was in love with you
Doh, doh, doh, doh
I told the witch doctor, I was in love with you
Doh, doh, doh, doh
And than the witch doctor, he told me what to do
He told me

Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting tang walla walla bang bang
Ooh ee ooh ah ah ting tang walla walla bing bang
Ooh ee ooh ah ah ting tang wall awalla bang bang

"Didn't you enjoy that?" asked Theodore.

"...I guess," said Meg.

"A little more enthusiasm?" asked Simon.

"Look, Meg, I know my brother can be kind of a nuisance sometimes, but I can reassure you, he truly cares," said Simon.

"If you're interested, I can hire a whole orchestra to perform for you," said Alvin.

"No, thanks," said Meg.

"I honestly don't think that would be necessary," said Simon.

"Fair enough," said Alvin. "But what else can we do about Meg?"

"We can perform something at her school?" said Alvin.

"You know that will take a lot of time, patience, and work?" said Simon. "Not to mention, all the students are probably already weirded out by us."

"They are?" said Theodore, who looked as though he was on the verge of tears.

"Look, they're high school students, they've never seen singing chipmunks," said Meg. "Okay, fine, feel free to perform at my school, whatever you want. Perform "Witch Doctor" for all I care."

"Witch Doctor?" said Alvin. "Funny, that's our most famous song. We'd absolutely love to perform that song!"

"I was being sarcastic," said Meg. "I'd honestly prefer it if you performed something else."

"Pardon?" said Simon.

"You know, something popular," she said. "Like, something to reassure me that I'll be okay in the long run. Something like the song you performed on my birthday."

"Birthday?" asked Alvin.

"Sorry, I meant the day we met," said Meg. "You know, that song "If I could be like that, I'd give anything. Reminds me of band camp!"

"Oh, that one!" said Alvin, dumbstruck. "That song by that band with the doors! You know, we typically don't perform the same song twice, so you'll have to find another one. Maybe something by the Beatles?"

"Too old," said Meg.

"We could do something from SchoolHouse Rock," said Simon. "Hey, if they're in school, they should be learning."

"That's for babies," said Meg. "Look, you guys look into this, and I'll let sleeping dogs lie."

"OOKKAYYY!" shrieked Alvin.

"Excuse me?" said Meg.

"Sorry, he always reacts to everything that way," said Simon. "Too many years of putting up with Uncle Dave made him that way."

"Okay, fair enough," said Meg, closing the door and turning off the light.
