A woman gets on a city bus. She looks at the driver and holds up one hand; 
the driver holds up two hands. Next, the woman points up; the driver points
down. Then, the woman grabs her breast; the driver grabs his crotch.
 
Finally, the woman grabs her butt and gets off the bus.
 
A curious passenger asked the bus driver what the odd motions were all about.
The driver explained, "The woman is a deaf-mute. She asked me if a bus ride
is five cents, and I told her it was ten cents. Next, she asked if the bus
was going uptown, and I told her it was going downtown. Then, she asked if
the bus was going past the dairy, and I told her it was going past the 
ballpark..."
 
The passenger interjected, "Okay, but why did she grab her butt as she left
the bus?"
 
The driver continued, She replied "Oh shit, I'm on the wrong bus!"
