Ping pong players light bulb joke

Question: How many ping pong players does it take to change a lightbulb?
Answer: Four. One to complain that it's "table tennis" not "ping pong", one to change the lightbulb, one to protest about the type of glue he used to fix the lightbulb into place, and one to get out his copy of the "Bats 'R' Us" catalogue and point out that he could have bought an even better one for 50p less.
