The bartender, feeling sorry for Paddy, tries to think of somthing he can do. "Why don't you try shaving the tail of one of the horses?"

Paddy stops crying and says. "That sounds like a good idea, I think I'll try it."

A few months later he comes back to the bar in worse condition than he was before.

"What's the matter now?" The bartender asks.

Paddy answers. "I shaved the tail of one of the horses (sob, sob), but it grew back and I can't tell them apart again!"

The bartender, now just wanting him to shut up or leave says. "Why don't you try shaving the mane, maybe that will not grow back."

Paddy stops crying, has a few drinks, and leaves.

A few months later he is back in the bar. The bartender has never seen anybody in this sorry of a state. Without the bartender even asking Paddy breaks into his problems.

"I.. I shaved the (sob) mane of one of the (sniff) horses, and... it... it... grew back!"

The bartenter, now furious at the Paddy's general stupidity, yells. "for crying out loud, just measure the stupid horses. Perhaps one is slightly taller that the other one!"
Paddy can not believe what the bartender has said and storms out of the bar.

The next day he comes running back into the bar as if he had just won the lottery.

"It worked, it worked!" Paddy exclaims. "I measured the horses and the black one is two inches taller than the white one!"
