I went to the beach and saw a crab playing a guitar.

I used to be addicted to soap, but I'm clean now.

Why did the piano get in trouble at school?

Because it kept key-ing off its classmates.

My son came home from school yesterday looking a bit deflated. He told me he'd really struggled with his math test, especially the questions about decimals and fractions.

I told him he just needed to get to the point.
