Man and friend are smuggling a quantity of cigarettes across the Sahara
As they trudge along leading their laden camel one of them says to the other "Stop that fvcking counting"
The other guy says "I'm not counting"
"Yes you are I can hear you"
The argument develops and in a rage the first guy pulls out his revolver and shoots his mate.
The following day he notices that he can still hear the counting "One, Two, Three, four etc"
He knows he shot his mate and left the corpse behind and he can't figure out where the sound is coming from.
Then he notices the camel's jaws moving (the way camels do) and he becomes convinced that it is the camel that is making the noise so he shoots it.
Then he has to struggle on carrying the load of cigarettes himself
On the third day he hears the counting again "One, Two, Three, Four etc"
Convinced that he is going mad he shoots himself, as he falls to the ground a pack of cigarettes drops in front of him and his last sight is of the legend "Its the Tobacco that Counts"
Collar, lead, walkies!
