What would あなた do if some came up to あなた and smacked あなた with a fruitcake?

Slap them with a pie.

Honestly, I'd probably tear up if it hurt and just walk away.. I don't like fighting and I would probably be so fahking confused. XD

i say thank you.. and eat it ^_^

I'd poke them in the eyes Moe Howard style.

i would say sick them Pookie

I'd yell "JERK" and make them eat it. *laughesanevillaugheventhoughitwasntevilatall*

....

Start crying.
Im so wimpy :(.
Then i'd call my bestfriennn Johnathon to come kick their,ass c:.

Probably 質問 into why the certain person did it and then if it was a joke, giggle about it. But if it was something serious, than I probably would not make a big deal about it and 移動する on.
