Original request:
I have this bad habit of singing this little diddy that includes:
Happy happy
I’m so
Pee-pee!
Kev thinks I just made it up like the thousands of other random jingles I sing that I legitimately did make up, but I swear this is from a real song.
I tried to Ask Jeeves, but that dummy didn't know anything about it.
Does anybody know?
