Is this why Futurama doesn't use the birthday song?

[Sacred Jellybean]

Yeah, I learned about this from a friend in college, but it's not exactly common knowledge among everyone. This is why if you go to a restaurant on your birthday and someone decides to be dick and tell the waiters to sing for you, it's never the actual birthday song, always some silly variation of a public domain song, like the military marching song ("I don't know but I've been told, they say Alaska's mighty cold" etc).

I first typed that out as "pubic domain", god damn mind in the gutter. D:
