I met Baba Brinkman at TAM London, and wasn't sure what to make of him. He's a big guy, noticeably white, and raps. About evolution. OK then. Well, being a skeptic I had to wait for the evidence. So when he performed on stage I was attentive, and my scientific curiosity was quickly satisfied: he's the real deal. He's a great rapper, spontaneous, funny, and very intelligent. He had everyone in the audience rapping with him, which was awesome to behold. And, via Hemant Mehta's The Friendly Atheist blog, you can see for yourself: Cool. If you get a chance to see him perform, take it. Word*.
