I've heard all of the above more than I care to think about, but one stands out: the naked pillow fights.
I once told my then-fiance & his non-greek friends that, in four years of college, I never once took place in a pillow fight, let alone a naked one. When I said that, the one guy said, "Oh, come on! We need something to fantasize about!"
So, it's become a standard joke: "Yes, we took Quota and made Total and had the Homecoming Queen, and yes,
still found time for our nightly naked pillow fights!"

Sometimes, making fun like that makes for better relations.
