Hahahaha, the whole story was ridiculously funny but this line: "Then Merlin shined his heavenly light upon them, Salazar Slytherin clapped Gryffindor on the shoulder, cute angels sang, and Harry and Draco’s cocks were rubbing hard against one another. It was without any question the best sensation in the history of nerve endings." I can't even.
XD
I also loved Neville and Harry's date. (And Harry and Draco in the bathroom *o*, and Draco's second fantasy XD)
