In no time, Beavis and Butt-Head were with Egon in front of a large, red structure, as big as the wall it was standing against. It was the containment unit, where the Ghostbusters stored every ghost they captured.

"You see boys, after we contain the entities in the traps, we bring them here to store them indefinitely. This model was a big improvement over what we originally had to work with. Now if you look here, you can see –". Egon was interrupted by the phone ringing upstairs. "I'm sorry, I need to get that. We're shorthanded this week. Just stay put." He ran to get the phone.

Beavis and Butt-Head, of course, weren't paying any attention. "Finally," exclaimed Butt-Head. "It's a vending machine!"

"Yeah, seriously," agreed Beavis. "Dammit… I don't know what I want, without the pictures!" He began pressing random buttons on the console.

"Dammit Beavis, you're taking too long. It's my turn!" He begins to hit buttons of his own.

"Get out of the way, fartknocker, I still don't have what I want!"

They got in each other's way, and began fighting, all while hitting buttons. In the commotion, the main switch was pulled. They ceased their squabble in time to witness a telescoping hatch open up, and smoke billow out.

"Way to go, Beavis, you broke something else." Butt-Head said.

"Shut up! I didn't do it, you did!" answered Beavis.

The smoke cleared, and moments later, a tiny Stay-Puft Marshmallow Man floated from the hatch.

"Hey Beavis, isn't that that famous Marshmallow dude?"

"Ohhhh, yeah!" he exclaimed. "He's cool, but isn't he supposed to be, like, bigger?"

"Who cares? Huh huh. At least this way, we can catch him for a snack. Now shut up, grab a backpack and follow me!"

Upstairs, still on the phone, Egon notices Stay-Puft floating into the lobby. He does a double take. "Mom, I'm sorry, but I really have to be going now. Call you next week." He slams the receiver down as Beavis and Butt-Head follow the Marshmallow Man upstairs.

"Holy Heisenberg! What on earth have you done?" exclaimed Egon.

"Uhhh, we're just catching a snack, sir," answered Beavis. "By the way, does your vending machine have, like, a chocolate syrup dispenser, or something?"

"You don't understand! You've unleashed unspeakable danger on the whole city! Calm down… No need to panic, gentleman. I'll just need to contact the guys and get them here, ASAP." Egon runs back to the phone, while Beavis and Butt-Head go outside to find Stay-Puft.

"Uhhh…Where'd he go?" wondered Butt-Head. Suddenly, a shadow cast across the boys.

"Butt-Head?" Beavis poked his buddy in the ribs.

"Ow! Quit it, Beavis!"

"Butt-Head, look!" Beavis pointed up. They were both stunned at what they saw. The Stay-Puft Marshmallow Man had grown to his full size. Any other person on earth would have been frightened beyond the capacity for rational thought. Beavis and Butt-Head, however, were too dense to be scared.

"Whoa! See, Butt-Head, I knew he kicked ass."

Butt-Head turned on his proton pack, and began shooting at Stay-Puft. It was made easier, since the Marshmallow Man was such a huge target.

"Hey, hey, hey! Stop it, butthole!" Beavis shouted. "What do you think you're doing?"

"Dude, settle down," said Butt-Head. "If we shoot at him long enough, we can make S'Mores! Now, shut up, turn on your pack, and start shooting!"

"Huh huh... Yes sir, Butt-Head, sir!" Beavis activated his pack and began shooting with Butt-Head. His aim wasn't as graceful, but they both kept on the mighty behemoth at full blast, determined to break him down to something edible.

Beavis' jerky handling of the particle thrower eventually caused his stream to cross with Butt-Head's. At that moment, at least three city blocks were blinded by a huge explosion. The boys were thrown backward onto the concrete. When the smoke cleared, everything around them was covered by marshmallow goo.

"Whoa!" exclaimed Butt-Head, getting his wits about him. "That totally ruled!" Egon rushed out.

"Boys, what was that terrible sound?" He got a good look around him. "Oh, my gosh! Well, at least the others will be here any minute now. Are you okay?"

Beavis spoke up, as he picked charred marshmallow off a neighboring building. "No! This marshmallow tastes terrible. You suck! Butt-Head, let's get out of here!"

"Uhhh, okay." They dropped their packs on the gooey ground, and began to walk off.

Egon started to protest, but realized it was futile. No irreversible damage was done. Just then, Ecto-1 pulled in front of the firehouse. Ray, Peter and Winston slowly got out as they surveyed the damage.

"Whoa, this looks great!" exclaimed Ray. "What on earth did we miss?"

"I don't know," said Peter. "But I'm guessing I'm glad we did."

"Ditto, man." added Winston.

"Fellas," said Egon. "The next time I recruit anyone from NYU, I'll make sure I'm working as a professor there first."

Beavis and Butt-Head are walking down the New York City streets, tired, hungry, and covered with slime and marshmallow. Butt-Head pipes up.

"Hey Beavis? Huh huh…"

"Yeah, Butt-Head?"

"You look like you had an accident! Huh, huh, huh, huh."

"Shut u- Ohhhh, yeah, I get it now. You too, Butt-Head. Huh, huh, huh, huh…"

The End
