Kids: What's inside, mints?!?
Fred: I don't know, why don't you shake it.
Kids: (shaking) It sounds like mints!
Abby: Well, let's smell it to see.
Daniel: (sniffing) I can't tell, it just smells like box...
Also:
The other day I mentioned to Daniel that he probably needed a bath. He sniffs his arm and says "no, I'm not stinty (stinky), I just smell like stin (skin)!
