I love sitting down for the training and saying 'ok, I've been jumping for about 4 months, I've got 14 jumps, and they say I get to take you today!'. I had a mother look at her daughter on her 18th birthday and say 'is he serious??' asking her like I wasn't even sitting there.
I like the 'lump in your throat' one, that always gets a howl with a bunch of macho guys jumping together. Or saying, '-TM- is the best gay tandem instructor we have!' (stole that one from the guys at emerald coast, thanks guys!)
We also have a TM that says 'put your dick in the wind, or I'm going to put my dick into you!'... worked good until one guy jumped up from the back and said 'I wanna jump with him!!'
We're all here to have safe fun.
