The Big Bang Theory, Season 6

[Penny, Amy, Leonard and Sheldon kneel around the coffee table, each has a blueberry pie before them]

Penny:
Alright, standard State Fair pie eating contest rules are no hands, first one to clean the pan wins.

Amy:
On the count of 3. 1... 2...

Sheldon:
Wait. I'm a little concerned. Blueberries are rich in antioxidants.

Leonard:
So?

Sheldon:
So with all those antioxidants, what if I run out of oxidants?

Leonard:
Sheldon, we haven't won a game all night. Now you either stick your face in that pie or I'm gonna stick that pie in your face!

Sheldon:
That's rude.

Amy:
1... 2... 3... EAT! [all four dive in face first then Howard arrives]

Howard:
Hey guys, guess who's back from space!

All four:
NOT NOW! [Howard leaves]

Sheldon:
Oh! Ow! Blueberry in my nose! Blueberry in my nose!

Leonard:
Snort it down and keep eating!
