Thanks for your help! The slides played beautifully. Unfortunately there was a girl in the front row who was laughing hysterically intermittently during my entire 15 minute presentation. I was sure that something was wrong with the projector, or that my fly was open. Anyway, I approached her after class and asked her why she was laughing, and she said: "Oh, it's just that you were so serious. Like a 30 year old man!" Keep in mind that this project was about the genetics of monamine oxidase genes, so I'm not sure what else she was expecting...
Weirdest presentation ever.
