Ummm, okay, I got it, I got it.
A horse walks into a bar and the bartender says, "How did those doors get so damned big?"
The horse approaches the bar, smiling politely, but then continues to wrench his face uncomfortably into a bitter scowl.
The bartender stares him down, trying to assess his dour mood. Then, deciding that it isn't too polite to pry into the matters of his new customers, he asks, "What'll you have?"
The horse moans dramatically and places his head sullenly on the bar. He sighs. He obviously needs a friend with which to share his feeling. To the bartender, he's just another unpaying loiterer.
Then, the bartender, realizing that it's Friday, decides to take inventory before the boss comes by to check the books. The bartender worries that he may have been a bit too generous with the free shots he'd been serving...
Wait, I'm telling this wrong.
