That's Disgusting

I was sitting on the floor in Tucker's room, trying to beat him at a racing game. Sam and I were there to avoid our parents. All of a sudden I smelled corn.

"Hey, Tuck, how early does your mom start dinner?"

Tucker: About 5-5:30. Why?

"I smell corn."

Tucker: It's only 3, dude.

"Then why do I smell corn?"

Sam: I smell it now too.

We looked at Tucker who was quickly turning red from trying not to laugh.

Both of us: Out with it, Tuck.

Tucker: I just farted.

"That's DISGUSTING!"

Sam: I agree.

Tucker: Excuse me?
