Here is a nice joke from the outback in Australia....
A worker on a sheep farm had a bad habit of always taking a crap in the bushes whenever the boss needed him. The Boss got tired of this and told the worker "if you keep crapping so much, your guts will fall out". The worker didn't listen and the next day when the boss was looking for him, sure enough he was in the bushes crapping again. So the boss had an idea, he went and found a dead sheep in the paddock, removed its guts, then stealthily placed the guts under the worker crapping in the bushes.
Later on that day, the worker looking rather ill, came up to the boss and said "you know how you said my guts would fall out, well they did! and although i didn't feel them coming out, i had a terrible time getting them back in!!
