Yo' Mama

A real-life example of how quickly a conversation with a toddler can degenerate:

3YO:	[My cousins] call Mommy zia!
e:	Do you know why they call her that?
3YO:	They...they don’t know her name!
e:	(Hiding laughter) Well, your mommy is Italian and zia is Italian for aunty. Like how Dora calls her aunty tia in Spanish.
3YO:	Your mommy's Italian!

I didn't realize that they taught the dozens in pre-school, but I suppose it's never to early to learn quality yo' mama jokes.
