Two workmen were sitting in a pub drinking and arguing about which pub they should visit next. "The Rose and Crown's the closest," said the first workman.
"No, the Elephant and Castle is closer!" the second workman argued.
Eventually they decided to go to the Elephant and Castle. But on their way to the pub in question a ferocious lion which had escaped from the local zoo lunged at them. Just as it appeared they were going to be lion chow the beast was killed by a sudden burst of machine-gun fire from a search plane that happened to be passing overhead.
Much relieved and waving their thanks to the plane crew they stepped over the lion's body and continued on to the Elephant and Castle, thereby proving that the shortest distance between two pints is a strafed lion.
