me and the wife in los angeles a few years ago, got a room and noticed a lady who went to high school with my wife (dont think they liked each other much) who was checking into the room right next door with 2 guys. we went at it and when we were done we heard them LOUDLY going at it next door, so we then go at it again but very loudly. then they did again, then us again, like it was some kind of a war or contest....after about 4 hours they won.
