A bloke is driving around in the Australian bush and because it's Australia his truck has got a 'roo bar' on the front that protects it if he hits a kangaroo.
Suddenly he hits something, so he gets out and sees that there's a pig wedged between his 'roo bar' and his truck.
He tries to get it out but it's stuck tight, so he gets on his CB radio and asks for advice. "Breaker breaker. I've got a pig stuck behind my 'roo bar. How can I get it out?"
A reply comes back. "Just slice open the pig and let the guts spill out. The pig will fall out."
So the guy does this and as predicted the pig falls straight out. "OK, I've cut open the pig and it's out, but now I've got another problem."
