Good Idea: Having six Scottish Terrier puppies drink from the same bowl. (Having six Scottie pups seems like the best thing in the world anyway, but making them into a pinwheel? Genius) 

Bad Idea: Motoring over sand dunes in a jeep when you don't know what's on the other side, and then flooring it when the car is on it's nose. This is what you get for trying to look cool guys.
