The boss walked into the office one morning not knowing his zipper was
down and his fly area wide open.  His assistant walked up to him and
said,
This morning when you left your house, did you close your
garage door? 'The boss told her he knew he'd closed the garage door, and walked into
his office puzzled by the question.As he finished his paperwork, he suddenly noticed his fly
was open, and zipped it up.He then understood his assistant's question about his
'garage door.'  He headed out for a cup of coffee and paused by her desk to
ask, 'When my garage door was open, did you see my Jaguar parked in
there?'
