Dear all, I heard this shell joke through my dad.
I have never heard it before, maybe it's new. Oh
well, Enjoy!

Once there was a snail who had been mugged
by a turtle. In the aftermath, the authorities questioned
the snail in hope of getting info on the suspect. "What did
he look like?" they asked him. "I, I'm not sure." Replied the
snail. "It all happened so fast!"
