A bunch of my friends are preggers these days, and I just keep finding geeky T-shirt slogans that I want their babies to wear on onesies. This is my new favorite, made by The Affable Atheist store on Cafe Press* and introduced to me by paleo-blogger and stand-up hominid Brian Switek.

*Also purveyors of "If You Can Read This, Thank an Evolutionarily Successful Hominid" bumper stickers.
