Take a potty and run

The story:

I was chilling out, listening the classic rock radio station, and singing along. And of course, as soon as I got the the "potty" part, my roommate walked in. She started laughing and asked what the hell I said. I told her, and she laughed some more. She said "You fool, it's 'take the money and run.'" I didn't believe her until the radio announcer dude said the name. Yeah...never singing THAT song again...
