"On the Senior Bus" joke
A bus full of senior gamblers was driving down the freeway, returning from two days in Las Vegas. A lady passenger comes forward and complains loudly to the driver that some male creep is crawling along the floor and has had the temerity to fondle her. The driver tells her he'll stop as soon as the opportunity presents itself.
As the driver was searching for a good spot to pull over, another female passenger comes forward, complaining of being fondled, too. To the driver's mind, this constitutes an emergency, so he immediately pulls over onto the shoulder and brings the bus to a screeching halt. He proceeds to go back to find the culprit and spies this little baldheaded guy crawling on all fours along the floor of the bus. He confronts the guy and asks him what he's doing on the floor.
"Well," replies the little fellow, "I lost my toupee a few miles back and I thought I'd found it twice until I realized mine's parted on the side."
