The only logical thing

Last night while cleaning theatres, we found a CD on the floor under one of the seats.  It was a set of audio lessons for how to make elk mating calls.  We were all baffled; why the heck someone would take this into a theatre with them?  In the end, we did the only logical thing we could under those circumstances: we stuck it in the CD player in the back room and played it over the PA system.  Customers were equally baffled, but it was fun to watch.
