On Mythbusters tonight, they tested the MacGyverism from The Wish Child episode where he used gunpowder and the butt of a gun to blow open a door lock. Unfortunately, it didn't quite work the way they show it in the episode.

For once, I would love for them to do one that does work.

At least they said the principle of the idea was sound, though.
"If a man does not keep pace with his companions, perhaps it is because he hears a different drummer."
