Ellora's Cave's Blog has an amusing competition for the best "How many xxx's does it take to screw in a light bulb?" which should be writing related in some way:
Go and read - they are all funnyThese were mine:
Q: How many m/m authors does it take to screw in a light bulb?
A: Only one, but there will be liberal amounts of lube, and three fingers inserted first to make sure it fits.
Q: How many agents does it take to change a light bulb?
A: Dear Author.
I'm sorry but your light bulb isn't suitable for this socket. We apologise for the lack of a personal response but as you can imagine we get so many light bulbs offered we are unable to screw them all in.
We wish you luck finding a socket elsewhere.
I look forward to reading yours!
