Sherlock Holmes and his friend Watson were on a camping and hiking trip.
They had gone to bed and were lying there looking up at the sky. Holmes said, "Watson, look up. What do you see?"
"Well, I see thousands of stars."
"And what does that mean to you?"
"Well, I guess it means we will have another nice day tomorrow. What does it mean to you, Holmes?"
"To me, it means someone has stolen our tent."
Snails produce a colorless, sticky discharge that forms a protective carpet under them as they travel along. The discharge is so effective that they can crawl along the edge of a razor without cutting themselves.
