Bad songs to have in your head

I saw this stand-up comedian on Comedy Central the other night whose whole act was done in song. The idea was that he was supposed to be a children's entertainer singing songs to all the "boys and girls" of the audience. He actually was a really good songwriter/singer, which is probably why I've had one of his songs stuck in my head for the past two days. It's a lullaby to his child explaining why mommy doesn't live with them anymore.

...Daddy likes porno and ten-dollar whores,
Daddy gets drunk and he robs liquor stores,
Daddy's got sores on his naughty bits oozing with pus,
And that's why your mommy left us ...

It's actually a really pretty song. Too bad I can't sing it at work.
