Here’s a joke, that my colleague, George, told me yesterday:

Two turtles are creeping the desert. No water around, sun is burning hot, thirst is killing them. Suddenly they see a canteen and run over, but it’s empty, so they move on. A month passes by and they find themselves in front of a huge, beautiful oasis, full of water, trees and freshness. The first turtle says:

“Oh my, great! I’ll go back and grab the canteen we saw earlier. DON’T drink without me!”

“Fine, don’t worry. I’ll wait for you.”, says the other. So the first one moves away and the second starts waiting. And waiting. And waiting.

A month passes by and she’s thinking “He must be there now.” Another month passes by and she’s thinking again “He must be here any minute now..”

But he isn’t, so she’s thinking “I’ll wait another half month out of solidarity”

At one point, tired of waiting, she leans over the water and is just about to touch it with her lips (or whatever kind of mouth they have) as the first turtle jumps out of the bushes and shouts:

“Damn it! If we’re gonna be cheating I won’t even go!”
