A farmhand is driving 'round the farm, checking the fences. After a few minutes he radios his boss and says, "Boss, I've got a problem. I hit a pig on the road and he's stuck in the bull-bars of my truck. He's still wriggling what should I do?''
"In the back of your truck there's a shotgun. Shoot the pig in the head and when it stops wriggling you can pull it out and throw it in a bush."
The farm worker agrees and signs off. About 10 minutes later he radios back. "Boss I did what you said, I shot the pig and dragged it out and threw it in a bush."
"So what's the problem now?" his Boss snapped.
"The blue light on his bike is still flashing!"
