I totally ripped off an idea that someone, uh, floated on here before (I seem to recall it was Goofus speaking of a friend of his, but I could be wrong-- if not, he sure is a likely source):
I have sucessfully taught my two-year-old son to refer to his feces as "dodgers." It's quite, quite hilarious. He announces whether he has dodgers in his diaper, and sometimes says "stinky dodgers" just as a courtesy warning. I can't wait for his reaction in a few years when he learns that someone named a baseball team for poop. His confusion and amusement should be something to see.
He also has a natural and powerful left-handed swing, so, naturally, I have started him on steroidal cream and HGH.
