A man walks into a bar with a giraffe.
He walks up to the bar and takes a seat, the giraffe does the same. The man orders a beer for himself and a double scotch for the giraffe.
They both proceed to drink and after a while they order the same again. They continue all night, ordering the same drinks, drinking them and ordering another load untill suddenly the giraffe falls off his stool and lies unconscious on the floor.
The man gets up of his stool and heads for the door,
The barman shouts at him as he heads out the door ‘You can’t leave that lyin’ ‘ere!’ to which the man replies, ‘Its not a lion its a giraffe!
