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 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 went 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!"
