A group of people were traveling cross-country on a Greyhound bus.  The
driver had just turned onto the Interstate highway when a woman came up
to him and said, "Please stop the bus, there's a man back there who's
bothering me."

The driver said he would stop at the very next exit but before he got
there, another woman came up and made the same complaint, but this woman
added, "This guy's a real pervert!"

When the driver was finally able to stop, he walked to the rear of the
bus and saw a little old baldheaded man, down on his hands and knees
looking under the seats.

The bus driver said, "Sir, what seems to be the problem?"

"I lost my toupee and I'm looking for it. I thought I'd found it several
times, but mine parts on the side."
