"What's worse - stapling ten babies to one tree, or one baby to ten trees?" is one I've heard. Actually, first time I heard it was from a friend who was telling it to the science teacher when he didn't realize she was pregnant...
I wouldn't call it funny. I don't think there's quite a word for it. It's one of those things where you huff, in a fashion which could almost be called laughing, and shake your head while reflecting on just how messed up society is. It brings to mind this song.
Specifically the opening lyric, which says
"The world's on fire but we're all smiling
Though it's all our fault
But life is short so we resort to laughing through it all"
