A joke

Husbandio told me this the other day, and since I'm feeling a little brain dead after a busy weekend I thought I'd re-tell it here rather than thinking of something original to write. Apologies, but it is funny, so here goes.

Two Mexicans, Juan and Pedro, are lost and starving in the desert. Suddenly Pedro spots a tree, draped with rashers of bacon.
"Juan", he cries, "we're saved". He dashes over to the tree, but as he reaches it he is suddenly gunned down in a hail of bullets.
Juan rushes over to him and as he gets there Pedro cries out "Juan, run! Is not a bacon tree, is a ham bush!"

Boom boom! Feel free to regale your colleagues with this on Monday morning...
