How to Host a Garden Snail Race
Many of the mollusks will be too skittish to come out of their shells. You want brave snails. Wait until one peeks out of his shell and starts moving. Grab that one and, while holding the shell in the air, press a racing number onto the shell. DO NOT apply the number while on the ground because you'll smoosh and possibly injure the snail.
What a great word that is, "smoosh." I should name my next cat "Smoosh." Anyway, we don't have snails here, really, we have slugs.
