Joe walks into a bar, very down on himself.
As he walks up to the bar the bartender, Mark, asks, "What's the matter?"
Joe replies, "Well I've got these two horses (sniff, sniff), and well… I can't tell them apart. I don't know if I'm mixing up riding times or even feeding them the right foods."
The bartender, feeling sorry for the guy, tries to think of something he can do.
"Why don't you try shaving the tail of one of the horses?"
Joe 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?" Mark asks.
Joe, in no condition to be in public, answers, "I shaved the tail of one of the horses (sob, sob), but it grew back and I can't tell them apart again!"
Mark, now just wanting him to shut up or leave says, "Why don't you try shaving the mane, maybe that will not grow back."
Joe stops crying, has a few drinks, and leaves.
A few months later Joe is back in the bar.
Mark has never seen anybody in this sorry of a state.
Without Mark even asking, Joe breaks into his problems. "I.. I shaved the (sob) mane of one of the (sniff) horses, and… it… it… grew back!"
Mark now furious at the guy's general stupidity, yells, "For fuck sake man, just measure the stupid horses. Perhaps one is slightly taller than the other one!"
Joe cannot believe what Mark has said and storms out of the bar.
The next day the Joe comes running back into the bar as if he had just won the lottery.
"It worked, it worked!" he exclaims.
"I measured the horses and the black one is two inches taller than the white one!"
