I have been scanning through the question feed here from time to time, because some of the titles (and in some cases, even the descriptions) of questions are very amusing when taken out of context:
- "I'm curious can I grow a banana which is rich in heavier unstable elements so that I can harvest and threaten my neighbor? (A single banana must be able produce fission reaction.)"
- "This question is inspired by a bowling ball"
You get the idea. If someone saw these question titles without knowing what the site is about, they would probably assume that everyone here is a mad scientist bent on destroying the world and/or universe.
My suggestion is this: Every so often, review the new questions, and create a meta post in which people can vote for the funniest title. The award would presumably be limited to bragging rights.
Obviously, it would be necessary to avoid people asking questions exclusively for the purpose of winning the contest, but that shouldn't be much of a problem.
