^ actually that can be really fun
well, never done it stark naked, but jumping out of a hot tub in the middle of winter to go roll in the snow then jump back in is very entertaining. Last winter me and a bunch of friends went to a party and the guy had a huge hot tub, VERY rich parents out of town for the weekend makes for a fun party. anyways, me and my friend decide we're going to jump out, make a few snow angels then jump back in, so after that, and the wonderful pain that comes from going back into the hot water, we get dared to run down the street in our bikini's. so never wanting to refuse a dare (alcohol was involved in this decision making process) we jump out and begin to run down the street. naturally, we started to get very cold very quickly, but we weren't going to give up on the bet that easily, so we ran to his neighboors house to borrow a pair of shoes (seemed like a brilliant idea at the time) unfortunately no one was answering the doorbell, and standing still was making the cold even worse, so off we were again. a few more numbed toes later we decided we'd had enough and returned triumphantly to the hot tub.
