When the Crocodile fails to catch Captain Hook (in Peter Pan), he swats his arm down in front of him. My 2 year old must feel his pain and is usually moved to announce
"Crocodile Say Dammit!"
Also, today a little kid on the playground surprised her somehow (didn't see it). She came running to me, crying, pointed at the kid and said
"Must Be Idiot!"
Don't think the kid's mom was too thrilled, although I found it most amusing.
Of course I did suggest some better words for her to say, but she just kept repeating "Must be idiot, must be idiot!"
Ah, my precociously verbal children!
