That was interesting, but I have heard similar stories before...
One of the guys that I work with is from South America, and he told me they used to play a game where they would actually have like competitions of who could "shoot" the farthest after.... being stimulated... I don't think they stimulated each other, more like do it yourself kind of thing.. i guess.
Kind of like a spitting contest, but not really.... ewwww.
Great works are performed, not by strength, but by perseverance.
