A man goes into a bar with his giraffe. They both go up to the bar and order drinks.
The man finds himself a bar stool and the giraffe props himself up at the bar next to his owner sipping his lovely cold beer. They finish off the first beer, then decide to have another. After finishing the second beer, they order another beer. Then another, and another.
Obviously starting to feel a little intoxicated by this point, and unable to control his long legs, the giraffe has to lay down on the floor next to his owner.
The man, decides to have one more for the road. He orders his beer and rather intoxicatedly drinks it. he decides that's it, he's had enough. So, he clumsily gets up from his stool, and proceeds to the door of the bar.
The barman shouts 'excuse me, are you leaving that lying there?' The man replies 'it's not a lion, it's a giraffe.'
