One day, my 12-year-old daughter Nyaniso came home with a library book that featured an array of clean jokes. That's great, I thought, since her tween world is full of songs, TV shows and movies that are anything but clean. She's an avid reader, and often I'm amazed at some of the material with vulgarity laced prose that's readily available to kids.

Long live clean jokes, I said. In fact, she inspired me to make up a list of jokes with the names of 12 U.S. Presidents. I admit that a few are corny:

1. Nixon

Knock, knock?

Who's there?

Nixon.

Nixon who?

Nixon Celtics are playing tonight. Celtics should win.

(Knicks and Celtics are playing tonight. Celtics should win).

2. Eisenhower

My friend asked, "How are you today?"

I replied, "I have an itch in my Eisenhower you?"

(I have an itch in my eyes. And how are you?")

3. Monroe

"Hey, Monroe faster! We'll never reach the shore at this rate."

(Hey man, row faster!)

4. Fillmore

I Fillmore anxious about this exam than my last one.

(I feel more anxious about this exam than my last one.)

5. Wilson

Wilson is the spitting image of his mother.

(Will's son is the spitting image of his mother).

6. Madison

Whenever James gets Madison tries to calm him down.

(Whenever James gets mad, his son tries to calm him down.)

7. Quincy Adams

Hey Quincy Adams car? What do you think he paid for it?

(Hey Quinn, see Adam's car?)

8. Lincoln

The railroad museum had an amazing display of Lincoln pin couplers.

(The railroad museum had an amazing display of link-and-pin couplers.)

9. Jackson, Harrison, Johnson

See Wilson.

10. Truman

It's Truman make mistakes, but to err is human.

(It's true men make mistakes, but to err is human.)

I have tried to make puns for the names of our recent three Commanders and Chief, but to no avail. Can you think of a play on words for Clinton, Bush or Obama?
