Q: What does a computer do when it is tired?
A: It crashes!

Explanation: Did your computer ever stop working (freeze) or turn itself off when you wanted to use it?  If it did, you can say your computer crashed.  Computer crashes are frustrating because you cannot get your work done, and sometimes you lose the work you finished most recently, unless you saved it.  Thankfully, they do not happen too often.

The word crash has other meanings.  If someone is tired, a person might say, “I’m going to go crash.”  This means that the person will go to bed and sleep.  Or you could say, “I crashed lat night at 8:30 because I was so tired.”

This joke is funny because it plays with two meanings of the word crash: A computer not working, and someone going to bed.

Here are two songs about another meaning of the word crash:
