My dad is a piano player

A grade school teacher was asking students what their parents did for a living. Timmy stood up and said, "My mom is a doctor!" Sarah stood up and said, "My father is a professor!" Little Johnny stood up and said, "My dad is a piano player in a whorehouse!"

The teacher couldn't believe what she's had just heard, so she made a point of calling Little Johnny's father that evening to discuss the situation. Little Johnny's father explained, "Actually, I'm a law attorney, but how am I supposed to explain that to a seven year old kid!"
