A man walks into a bar with a giraffe and asks for a shot of whiskey
The bartender asks him, "what is that thing and why's it in my bar?"
"That's my pet," the man replies. "He follows me everywhere and we both love a good drink."
Sighing, the bartender decides he doesn't have time to argue the semantics of bringing animals into bars and pours two shots, sliding them in front of the man. The first shot is quickly swallowed by the man, who then moves the second in front of the giraffe. To the bartender's surprise, the giraffe leans down, picks up the glass in his mouth, and gulps the whole shot down.
"Another round," the man says, putting a stack of money on the counter. The bartender obliges, and again the two companions down their drinks. This continues several times over, until both man and giraffe look well and truly sloshed. Finally, the man gets up, places a tip on the counter, then stumbles off of his stool towards the exit. The giraffe attempts to follow, but simply collapses unconscious on the floor.
"Hey!" the bartender shouts before the man can leave. "You can't just leave that lyin' there!"
"That's not a lion," the man slurs back, "that's a giraffe."
