Have you ever gotten an idea for a thread that you think a lot of people would enjoy, but decided not to post it for some reason?

I have a lot of ideas for threads, but 99% of these threads I end up forgetting or not bothering to post. These thread ideas usually come to me when I'm doing something and suddenly think of a question to center the conversation around. I don't think the Admin. would immortalize any of those threads in EoFF history, mostly because half of them were lame xD
