A teacher was quizzing her students and asked Johnny, "Who signed
the Declaration of Independence?"
He said, "Damned if I know."
She was a little put out by his swearing, so she told him to go home
and to bring his father with him when he came back.
The next day, the father came with his son and sat in the back of the
room to observe.
The teacher started another quiz and finally got back to the boy. "Now
Johnny, I'll ask you again. Who signed the Declaration of Independence?"
"Well, hell, teacher," Johnny said, "I told you I didn't know."
The father jumped up in the back, pointed a stern finger at his son, and
said, "Johnny, if you signed that damn thing, hell, you damn well better
admit it!"
