There are two guys who have been lost in the desert for weeks, and they're at death's door. As they stumble on, hoping for salvation in the form of an oasis or something similar, they suddenly spy, through the heat haze, a small tree off in the distance.
As they get closer, they can see that the tree is draped with rasher upon rasher of bacon. There's smoked bacon, crispy bacon, life-giving juicy nearly-raw bacon, all sorts. And the smell... oh, the glorious smell!"
"Look Pepe," says the first man. "It's a bacon tree!"
"You're right!" says Pepe, "We're saved!"
Pepe doesn't wait another second. He runs up to the tree salivating at the prospect of food. But just as he gets to within five feet of the tree, there's the sound of machine gun fire, and he is shot down in a hail of bullets.
His friend quickly drops down on the sand, and calls across to the dying Pepe.
"Pepe!! Pepe!! What on earth happened?"
And with his dying breath Pepe calls back: "Ugh, run, run!! It's not a Bacon Tree after all..."

"...its a ham bush!"
