Mr. Martin: Is this the fire department? Attendant: Yes, it is. What seems to be the problem? Mr. Martin: I'm stuck in a chimney. I'm calling from my cell phone. Attendant: What were you doing in the chimney? Mr. Martin: I lost my key, and I was trying to get into the house. Attendant: Gee, sometimes burglars get stuck in chimneys when they try to break in houses through the roof. Mr. Martin: Listen, I'm not a burglar. My name is Joe Martin, and I live at 219 Fourth Street. Now, are you going to help me or not? Attendant: I'll send a fire truck over right away. But Mr. Martin, I suggest you lose some weight, and not your keys.
