What comedian talks about Naming Vitamins?

Question

I was watching tv two or three days ago and there was a comedian who was really funny. He said something about when scientists were naming vitamins they got ahead of themselves, because they thought there were more than there actually are. "Vitamin A... Vitamin B.... Vitamin C.... we're running out.. just skip to Z."

I was just wondering. I'd really like to find his special. If you can help me, thanks bunches.
