Who here has come up with something that you didn't act on, and then you saw it somewhere? Maybe an invention, ad idea, etc. My favorite of mine that I haven't seen yet is an idea for a Preperation H commercial. Imagine a bunch of cowpokes on a cattle drive, and Johnny Cash's "Burning Ring of Fire" is playing in the background. One guy is riding on his horse and you can see he's in discomfort. Then the "should have used Preparation H" line comes in for a plug for the product. I think it'd be pretty damn funny and would grab some attention. I've had a couple inventions I'd thought up a few years ago, but can't seem to remember them now. Must not have been too good. What's everybody else got?
