Matter of interpretation...
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 pass the milk-farm, and I told her it was going pass the ball-park."
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!"
