When you get an old guy (preferably my g-pa) throw him on the ground and have him take a dump upwards like a train moving at high speed, and as the shit is coming upwards grab a condom and shove it over that then ram it in your ass like a monorail train thing.

SIDE NOTE: Lube might be helpful.
So last Christmas instead of giving grandpa the train set he's always been dreaming for, we performed a nice long monorail instead!
