Re: Part C:(Make up something): I was discussing this last night at dinner with a few friends. We came to the conclusion that the best solution when you know your joke or story is going nowhere, and it's going to die fast, is to just say "and then I found five bucks!" Simple as that.

So we were walking down the street the other day, and this guy looked at us and said, "can I shine your shoes?" We politely responded "no" and continued walking, then I started thinking about what to make for dinner. But then I found five bucks!

It just kinda makes the story worthwhile, because hey, you found a fiver!
