We brought them to our campus for a showing of The Room. Greg wasn't even supposed to come, but he tagged along. It's funny - Tommy will do something ridiculous (he would stop our waitress and tell these stupid stories or make stupid jokes) and Greg would just laugh at him and shake his head. He would quietly mock him throughout the time I was with them. I mean he obviously likes Tommy, but I think he just can't believe some of the stuff he does.
Honestly, my experience with Tommy was pretty limited, I talked mostly to Greg. He really liked Mad Men, which at the time was about to premier (last season). One of the funniest things was at the very end of the night when we were taking a group picture with Greg and Tommy and Tommy had to make the picture perfectly what he wanted. He spent like 5 minutes getting us all in the positions he wanted us in. And then there was no room for him so his solution was just to sit on me and assume I would make room, which I did.
