Same people who pull the wings off flies.
I am reminded of the scientist and the flea.
The scientist would clap his hands and the flea would jump.
He removed one of the flea’s legs and clapped an it jumped.
He removed another one and clapped and the flea jumped.
Finally with only one leg left, he clapped and the flea jumped.
Removing the flea’s last leg he clapped but the flea
just laid there...
Aha, he said, fleas with no legs are DEAF!
Yeah really.
