Phil Plait is a great speaker. If he's ever in your area, go see him. Especially if you are a geek. It's so nice to be around other people who get excited about astronomy the way I do.

Phil came and gave his Death from the Skies talk at OSU on 2011.04.28. Here he is talking about Kleopatra, the asteroid shaped like a dog bone.
