A senior citizens group charters a bus for an overnight gambling casino trip.  

An elderly woman comes up to the bus driver and says, 'I've just been molested!' 

The driver felt  that she had fallen asleep and had a dream.. So he tells her to go back to her seat and sit  down.

A short time later, another old woman comes forward and claims that she was just molested.  The driver thought he had a bus load of old wackos, but who would be molesting these old ladies? 

About 10 minutes later, a third old lady comes up and says that she'd been molested too. 

The bus driver decides that he'd had enough and pulls into the first rest area. 

When he turns the lights on and stands up, he sees an old man on his  hands and knees crawling in the  aisles.

'Hey gramps, what are you doing down there?' says the bus  driver.

'I lost my toupee(false hair).  I thought I found it three times, but  every time I tried to grab it, it gets up and runs  away!'
