This is gonna be fun

I made a bet 5 months ago with my trainer that at the end of the package I'd get to train him.  Well, we have 2 sessions left, though I renewed for more, and I've contacted his workout buddies and staff to devise a surprise.  He won't be expecting me, I think he's forgotten all about this, and I'll by lying in wait as he enters a workout room. Perhaps that day the tshirt should read:  My trainer kicks my behind...today I kick his!

How funny, you should have fun that day.
