Back in the days of the wild west, 3 Mexican bandits robbed a bank in a small town. As they were making their way out of town, they noticed a posse had started following them.
So the 3 bandits made their way into the hills and one of the bandits looks back over his shoulder and says "I think we lost them... We can slow down now."
After a little while they got tired and were looking for a place to rest, when they came across a stream with a tree next to it that had bacon growing on it.
They couldn't believe their eyes when they saw the bacon-tree and decided they would stop there for a while. So they stopped and were eating bacon from the tree and drinking from the stream. They were in the shade and were just beginning to get good and relaxed.
Suddenly the posse jumps out of the bushes and had them surrounded. The bandits jump up and hold up their hands and one says to the other two, "This is no bacon-tree!!!! It's a HAM-BUSH!!!"
