A/N: From this past week's new episode (which I have to say was remarkably better than the season premiere), I give you this oneshot I just thought up.

"Let's face it; there are good kinds of yeast and bad kinds of yeast..."

"Oh my God," Blaine muttered to himself, sitting in the choir room alone and watching from his phone. "This isn't...it can't be..."

"Hey, Blaine, what's going on?" Sam called, walking into the room, dragging his backpack behind him.

"Sam, come check this out. You will not believe this." Sam raised an eyebrow, released his backpack strap, and jumped over the chair to Blaine.

"But bad yeast goes scat with Yeast-I-Stat."

"Wow, Santana's doing a..."

"I know."

"Burns and itch are a thing of the past..."

Tina and Artie came in, chatting about prom nominations.

"If you were king, it'd be totally weird," Tina was saying.

"Guys, come here!" Sam was trying to hold his laughter in. Tina and Artie looked at each other and came over. Blaine held his phone in front of them.

"And Yeast-I-Stat's seven easy-step application makes feeling fresh a breeze..."

Sam began laughing as Marley, Jake, Ryder, and Unique entered the room.

"What the...?" Ryder looked at Sam.

"I like yeast in my bagel, but not in my muffin."

The four Gleeks began giggling.

"What's going on?" Unique asked.

"Not intended for young eyes," Sam panted.

"Did you hear the news? Let's have a chat. The yeast goes scat with Yeast-I-Stat."

A cheery voice rang out, "I'm free!"

The four looked at each other again and began howling with laughter.

"Where did you find that?" Tina breathed as she calmed down.

"It was on YouTube," Blaine replied. "Someone with the username," he examined his phone, "JB—oh, crap."

"Give me that." Tina yanked the phone from his hands. "Should we tell her it's online?"

"Yeah, I think we should." Sam got up off the floor and texted Santana.

"I think you should know. Your commercial is online. Blaine, Tina, Artie, and I saw it. –SE"

"What are you talking about, Trouty Mouth?"

Sam typed in the link and a few minutes later, a new text popped up.

"The second I come back, not only are you, Girl Asian, Wheels, and Scruffles in for it, but one Jew is going to see the bad side of Snixx."

"We're in trouble," Sam told the others, who looked at each other knowingly.
