A guy goes into a bar and says, “Quick, gimme a beer before the trouble starts!” The barman looks around the sleepy bar, shrugs and hands the guy a bottle of beer. The guy drinks it fast. “Quick! gimme another beer before the trouble starts!” The barman looks at the guy oddly but hands another beer to the guy. The guy drinks it fast. “Quick another beer before the trouble starts!” The barman hands him another beer, with a frown on his face, but hands it over reluctantly. Again, the guy drinks it fast. “Quick another beer before the trouble starts!” The barman replies, “Look pal, you seem like a nice guy, but maybe you should start paying your previous drinks”
“Now trouble is about to start!”

Three men walked in to a  bar. You think one of them would have seen it!

A man walks into a bar with a giraffe and they proceed to get blitzed. The giraffe drinks so much it passes out on the floor.
The man gets up and heads for the door to leave when the bartender yells, “Hey! You can’t leave that lyin’ there!” The drunk replies, “That’s not a lion! It’s a giraffe.”
