Who am I?

One Monday morning a mailman is walking the neighborhood on his usual
route. As he approaches one of the homes he noticed that both cars
were in the driveway.

His wonder was cut short by Bob, the homeowner, coming out with a load
of empty beer and liquor bottles. "Wow Bob, looks like you guys had
one hell of a party last night." the mailman comments.

Bob in obvious pain replies, "Actually we had it Saturday night.
This is the first I have felt like moving since 4:00 am Sunday
morning. We had about fifteen couples from around the neighborhood
over for 'Party Cheer' and it got a bit wild. Hell, we got so drunk
around midnight that we started playing WHO AM I."

The mailman thinks a moment and says, "How do you play that..?"

Well all the guys go in the bedroom and we come out one at a time with
a sheet covering us and only our "privates" showing through a hole in
the sheet. Then the women try to guess who it is."

The mailman laughs and says, "Damn, I'm sorry I missed that."

Probably a good thing you did," Bob responds. "Your name came up four
or five times."
