Fist Bumping

As many of you know I ride the ACE Train to work and back. It's an interesting experience as there's every type of person on the train. Janitors, Principles, Helicopter Pilots, etc. You name it, we have it. There is a group of older men that like to play poker on the way home and this is serious as there is money involved. Sometimes you will see $20's change hand. The reason why I point out this group is that all of them, mostly over 45 or so, think it is necessary every time they get on to the train is to greet each other with a fist bump. It's somewhat comical since many of them hang their fist out there for 30 or 45 seconds trying to get a bump where in fact they just look silly with their fist hanging out there. I found this on YouTube... This would be interesting to see in real life.
