We were just chatting in coffee and the topic of ‘light bulb’ jokes came up (along with some serious dubious jokes involving snowmen). Here are some astronomy examples of the staple ‘light bulb’ joke. Please add any more in the comments.

Q. How many physicists does it take to change a light bulb?
A. Eleven. One to do it and ten to co-author the paper.

Q. How many astronomers does it take to change a light bulb?
A. None, astronomers prefer the dark.

Q. How many radio astronomers does it take to change a light bulb?
A. None. They are not interested in that short wave stuff.

Q. How many general relativists does it take to change a light bulb?
A. Two. One holds the bulb, while the other rotates the universe.

Q. How many science fiction writers does it take to change a light bulb?
A. Two, but it’s actually the same person doing it. He went back in time and met himself in the doorway and then the first one sat on the other one’s shoulder so that they were able to reach it. Then a major time paradox occurred and the entire room, light bulb, changer and all was blown out of existence.

Q. How many infra-red astronomers does it take to change a lightbulb?
A. Two, one to change it, and one to bang on about the one they once changed while they were at the VLT.
