Sex-seeking male dolphins (in one species, at least) have wingmen to help "look for chicks." Really. Dolphins are turning out to be so human that, if we could just teach them how to lie, they could run for Congress.
COMMENT: Actually, they probably can lie. But would they want to be in politics? After a day hanging out with sea slugs, hagfish, sharks, and slime eels, why make it worse and be surrounded by lawyers?
