June 29th is International Day of the Tropics! Find jokes about it!

Why don't scientists trust atoms when vacationing in the tropics?
Because they make up everything, even the "sandy" beaches!

I once spent ten years marooned on a tropical shore...
I lived on nothing but coconuts and seafood. I fashioned sandals out of leaves, a hut out of grass and sticks, and I kept myself healthy with wild plants.
One day I was scouring the beach for copper wire to build the radio I was working on, and I came across a small white spheroid about 2" in diameter that I had difficulty biting.
The mystery was solved when a man stepped out of the trees and said, "That's mine." Astonished,
I asked him, "Where did you come from?"
He said, "From the golf resort just the other side of those trees."
