The night before we were leaving to go on Spring Break a few of my friends stayed the night at our townhouse. My sorority sister/roommate (Susan), who decided not to go to Cancun, decided she was going to go out to a bar and get completely shitfaced with another one of our sorority sisters.
We had to leave for the airport around 4am. Around 3am she comes rolling in and she wasn't very quiet. My friend (Jen) and her boyfriend (Dan) were sleeping on a couch in my living room and one of my sorority sisters (Kim) was sleeping on another couch.
I don't remember what was said to initiate her response but my drunk roommate said, "you gotta be fucking Jen!" Kim says, "I hope not because I'm on the other couch." That was two years ago and we still tease her about it almost everytime we see her.

I'll have to remember to bring that up this weekend
