Ive had contracts before, not currently. Usually for me they would outline a goal on part of both parties, a challenge. And the rules to abide by for both parties. If someone broke the rules they forfeit. So not traditional in the sense that clause one states im your property forever yada yada... but he made a claim, I made a claim, we see who wins.
The last one I accepted was I would stay there without running away or calling it quits for 6 months unless he forfeited, no rules as to what he could do to me, my day was planned out in morning, midday, and evening rituals and his challenge was he said he would fuck me up the ass(my original response was to laugh and say you can try) I signed over power of attorney, and signed consent waivers, and liability waivers(i doubt any of which would hold up in court) and we began.
