While playing operation he notices the little picture illustrating gas. It has a skull and crossbones on it:
Aaron: Mommy, does this mean that the guy has pirate farts?
Me: Um, well, sure Aaron.
While watching Wonder Pets:
Aaron: Mommy, do you know what oooooooo means?
Me: What Aaron?
Aaron: It means you like it in Spanish.
After hearing that my Dad was sick:
Aaron: Well suck me down a whirlpool!
When asked if he would like to learn how to play an instrument:
Me: Aaron, do you think that you would like to learn to play the violin?
Aaron: I already know how.
Me: You do not. Well, what about the guitar?
Aaron: I know how to play that.
Me: You do not know how to play the guitar. How about the piano?
Aaron: Mom, I already know how.
