In one of my interviews, the interviewer and I found ourselves in the very sterile office of a pathologist. Nothing more than a desk, a small attached bathroom, a shelf full of various path journals, and a small sign on his desk stating "interview not to proceed past this point" WTF?!
In the middle of the interview, a scratchy old pathologist entered without a word and walked into the bathroom. Without shutting the door, and in sight of both the interviewer and myself, proceeded to take off his shirt and pants. He stood there fumbling around with his wallet for a couple of minutes in nothing but boxers and a wife-beater (pardon the colloquialism) before redressing in a new set of clothes. We continued the interview as best we could until he left, at which point we both laughed hysterically. My interviewer was very cool, and even made some comment about how all the journals on the wall were probably just dust jackets for a huge, fifty year collection of porn, spouting off the names of 5 or 6 hardcore magazine titles; hustler, jugs, cream, etc... I was both dumbfounded and impressed at the honesty/casualness of the situation. EM docs rule.
