My girlfriends and I share a personal trainer at the local gym. One of the many tortures Chris has us do is run the stairs carrying weighted balls above our heads.
One day when Chris was not there, we were running the stairs without the balls. One of the older ladies that walks in the morning met us on the stairs and said, "Running those stairs looks hard." I replied, "It's a lot easier without Chris's balls on our heads."
Somehow that just didn't come out right.
