hehehe, I just sent you an email explaining it.
Reminds me of another nun joke. Ok God forgive me but it's cute.
The nuns go out with mother superior one morning for a bike ride. They go over a bump in the road and all the nuns go ahhh
ohh..ahhhh...mother supririor says, sisters. non of that. They go over another bump and again all the go.. ohh ahhhh. Mother Superior is now upset and says ok sisters you have been warned now back to the convert and put those seats back on your bikes.
