There is one, it takes a little time to prepare.
1) Gain weight and have a massive beer gut.
2) Shave all your body hair before you go in to a MP, this can not be done with a five o'clock shadow, you must get a message right after you shave.
3) Ask for super soaker oil slide, this is two bottles of oil you may have to pay extra.
4) Ask attendand to sit on your face.
5) Raise the upper part of your body until she starts to slide.
6) Watch attendant slide up and down your body like a roller coaster.
Most attendants will give you an extra 15 minutes of sliding because of the thrill factor. I have even had a time when all the Sliders were taking turns that were working that shift, this was an hour and a half of slide pleasure for me at no extra charge.
One time I had a whole shift and two female by-law officers enjoying the ride.
