How often are you drunk or otherwise impaired (whipped cream in a can, Benadryl, large pan to the head) and think, "Wow, I just thought of a really cool question for thequestionclub," but later forget it and remember only the thought of it?
If you actually remembered it, what kind of a question was it?
eta: this is a question that I thought of, knew I wouldn't remember, and typed up before I could forget it!
