> Two rabbits were eating lunch in a garden. One looked up to see a turtle coming in their direction. "Oh no, here comes the tortoise toward us. Let us hide among the lettuce."

Excuse me while I explain this joke to myself.
"A tortoise is a turtle, right?"
"More or less."
"So rabbits are faster than turtles?"
"No, silly. Turtles eat lettuce."
"And I guess that means that the turtle would find the rabbits. They picked the worst possible hidding place."
"Right. But why didn't they just run away."
"Rabbits are not very smart."
"Smarter than a turtle."
"Well, I've seen rabbits eat lettuce. By the time the turtle gets there, they will have eaten their hidding place."
"Maybe that's it."
"Ha!"
