you're a what?

I just had a conversation with my friend's two-year-old daughter, Lucy. It went something like this:

Me: Ooooo, Lucy, look at you all dressed up! Are you a chicken?
Lucy: No! I am FUCK!
Me:
Lucy: FUCK! A FUCK! I AM FUCK!
Me: Uh...
Lucy: FUH-UCK!
Lucy's mother: Duck! She means duck! She's a fucking duck! DUCK!
Lucy: Yeah. Fuck. Quack.

Happy Halloween!
