Do you have to wash giant African land snails?

One needs to retrieve a giant shovel from the shed and whack the snail. Of course, the snail will fight back viciously. It won't give up without a fight. It will creep up on ones leg and try to eat through ones pants. In that case only a chainsaw can save ones life - the leg, with the snail on it, needs to be cut off. After that, one needs to use the shovel again and kill the giant African land snail with a final shovel blow between the ears.
