Six Pack

So Austin can do that thing where you sit down on the floor without using your hands and return to a standing position, again, without pushing off the floor or balancing with your hands. The girls at work were so impressed, they made him come over and demonstrate.
After Austin was gone, one of the girls: Does Austin have a six pack from doing that?
I told Austin and we laughed and laughed.
Austin: If I had a six pack, it would hurt now from laughing so hard.
