2am during a heatwave in the uk me and an ex ran across the road naked to have sex In the park to be caught like rabbits in the headlights of a on coming car
Went out for a few drinks so went to the smoking area outside with a woman. Ended up going further round the back of the pub to have a quickie then went back in for some more drinks.
Probably not that crazy but in a tent at a festival once in the middle of the day. 1000s of people walking about outside, trying to keep the noise down!
