My daughter's favorite song when she was little was the one she made up, called "Poopy Diarrhea". She sang it loudly in places like store check-out lines and restaurants. It went:
"Poopy diarrhea!
Poopy diarrhea!
Poopy, poopy diarrhea!" etc.
Then she would recite family names and common objects within her range of sight. "Poopy diarrhea...Mommy!" "Poopy diarrhea...brother!" "Poopy diarrhea...candy bar!" You get the idea.
So it must "run" in the family.
It takes a lot to gross me out, but you are just the guys to do it!
