Okay, this wasn't my embarrassing moment, but it was for Mike Zazzarino (God rest his soul).
Mike was our TKE Pledge Master 1st Semester sophomore year.  One night the pledges "Kidnapped" Mike. Tied him up in a blanket; no cloths, no ID, only a blanket and flip flops.  Drove him to Philadelphia Airport and dumped him on a luggage cart in the pick-up area and left.  This was before security, before TSA, and people were different then as we all know.  Mike had to find his way back to PMC on his own.  Well we weren't that horrible.  Some stayed around to make sure he didn't get in real trouble.  Needless to say the next month was Hell on pledges.  Mike was a pretty good sport about it all-in-all.  Could you imagine doing that today?
