Two snipers are going through the desert when all of a sudden they come under fire...
"Spotter"... says the shooter, "find out where those shots are coming from!"
So the spotter takes out his scope and starts panning round... "I think I found them. There is a small shrub, covered in bacon, gammon, and pork chops"
"That's them..."says the shooter... "it's a ham-bush!"
