An undercover cop called at my farm in Derry yesterday evening...
“I need to inspect your farm for illegally grown drugs”, he said.

“By all means officer, just don’t go in that field over there”, I replied.

The cop exploded, saying “Do you know who the feck I am?! I have the authority of the government with me!”, he shouted before pulling a badge out of his back pocket, “Do you see this freaking badge?! This badge means I can do what I want and I’ll go wherever the feck I want, have I made myself clear?!”

I nodded politely, apologised, and went about my work. A short while later, I hear loud screams, looked up and saw the cop running for his life being chased by my angry bull. With each step, the bull was gaining ground and he seemed sure to be gored before he reached safety. The officer looked terrified and continued to run for his life.

I threw down my tools, immediately ran to the edge of the fence and shouted at the top of my lungs,

“Your badge, show him your freaking badge!”

I have a sort of similar one that joke reminded me of.

A SWAT team pulls into a farm and speaks to the farmer about why they are there. The detective tells the farmer "We have a report of an illegal underground drug lab operating under your field and are here to execute a search warrant." The farmer says "I don't know what's going on, but help yourself." The cops go tear apart his whole field then find nothing. The detective tells the farmer "I am sorry for the trouble, we found nothing and we are sorry for any trouble we may have caused you." The farmer says "No, thank you for investigating my report. You just saved me a week worth of plowing!"

Very good..
