good idea

In the heat of the moment, you might think it's a good idea to ride a shopping cart down a hill or see if you can catch a hammer thrown by your friend. Usually we realize after the fact, especially if these brilliant ideas go wrong, that maybe it wasn't so smart to do in the first place. In a similar vein, here are people sharing some of the dumbest injuries they've ever had.

You wake up with this pressing feeling that you've just come up with the most genius thought. Maybe it's an idea for a screenplay or a song, and the only way to get it out of your head is to get it on paper. Then the next morning you find your masterpiece. And it just says "gorilla napkins." Weird thoughts just make perfect sense when you're asleep.Twitter knows.

It can pay off to trust that spidey sense. Even something as simple as recording a conversation or moving your car can have lasting after-effects.

Sometimes the satisfaction of a heroic act itself is credit enough. Other times a national burger chain steals your idea.
