I was sitting on a plane that is traveling towards Seattle. And the guy next to me turns and says to me Hey, you going to Seattle?. Nope, San Francisco... I'll be parachuting off in about an hour. Here's your sign!
As we're staggering out of the hospital, I don't remember doing this because I was still high, but apparently I turned to the entire operating room staff and screamed "Hey! I'd better not see this on YouTube!"
