Good old Dai's at it again
Dai, not the brightest spark in the world, wins two raggedy old cart horses in a local county lottery and he's having great difficulty telling them apart. He can't wait to tell his pal, Emrys, of his good fortune though. He telephones him to give him the wonderful news.
"I've had a great stroke of luck Emrys. But, I'm having a hell of a job telling which horse is which.".
"Isn't there anything? Nothing at all to tell them apart?", asks Emrys.
"I'll check again.", says Dai, and puts the phone down.
Luckily, on closer inspection, Dai notices that one of them has no tail. None whatsoever! "Marvellous", he thinks. "I'll have no problem now.".
Unfortunately, one day soon after, this horse gets his tail caught in a fence and, in a panic, tugs away and wrenches it clean off!
Dai phones Emrys with the disasterous news. "Now, how the heck do I tell which is which?", says Dai.
Emrys suggests he nicks a little piece out of the ear of one of the horses. Dai thinks this is a bit drastic, but a great idea nonetheless. A few weeks later, however, the horse with the 'nickless' ear gets it caught on barbed wire and suffers a nasty injury resulting in an identical 'nick' to the the horse with the nicked ear.
Panicking slightly, Dai rings Emrys again. "What do I do now Emrys?", asks Dai.
Then Emrys has an idea. "Why don't you measure the height of the two horses and sees if they're heights are slightly different?".
"That's a brilliant idea!", says Dai, and off he goes to measure up.
A few minutes later Dai runs back to the phone and dials Emrys excitedly.
"Emrys!", he says, "that was a fantastic idea. I'll have no problem telling them apart now.".
"Were their heights different then?", asks Emrys.
"Yes! By quite a bit!", says Dai. "In fact the black one is nearly THREE INCHES taller than the white one!!!!!!!!!!!!".
