when i was a kid there was a little toy available - i think they called them Mexican jumping beans - consisting of a capsule with a LIVE worm inside. God knows what type. probably infested the whole country. i don't know where they came from, but all of a sudden they weren't available, and they were very popular.
I remember "mexican jumping beans" from my childhood, too. Of course, they were probably immitation worms, not real ones.
'Face, the idea of something jumping up and down in the balls might have potential.
Whadd'ya think, gentlemen?
