What did the guitar say to the musician?

Pick on someone your own size!

I took my car into the shop the other day because it was making a weird knocking sound under the hood. The mechanic spent a long time listening carefully and checking all the hoses and belts.

He said he needed to do some intensive car-diology.

I decided to sell my vacuum cleaner; it was just gathering dust.

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.
