HAHAHAHA! I'm sorry, but that is just funny.
About the issue at hand, I think if it were me, I'd leave a note on the door suggesting afternoon delight. This way, you're not really saying "SHUT THE HECK UP I NEED TO SLEEP UP HERE!" but rather, "Wouldn't that be nicer in the afternoon?"
You could wait a while and see if you're stamping around worked or not. Then try the note, and if that doesn't work, send another a little more strongly worded suggesting that you are considering filing a complaint with the sup.
