Here is a weekend joke from the kim komando column.
A WEEKEND JOKE
Customer: My keyboard is not working anymore.
Tech Support: Are you sure it's plugged into the computer?
Customer: I don't know.
Tech Support: Pick up your keyboard and walk 10 paces back.
Customer: Okay.
Tech Support: Did the keyboard come with you?
Customer: Yes
Tech Support: That means the keyboard isn't plugged in.
[...long pause...]
Customer: But, I have a wireless keyboard. Where does it need to be
plugged in?
