I used to help run 3 Day Startup San Antonio. Part of the format is that the first night includes pitches by a select number of people hoping to get voted into the top X ideas that are worked on for the rest of the weekend.

We once had a guy whose first slide was just an NDA in tiny font that he actually read aloud to 50 people. I was in the back of the room with some of the other staff and I had to step out because I was laughing too much.
