Chap walked into a pub with his giraffe. They sat in the corner of the bar, it was a high ceilinged place, and started boozing. After about 7 or 8 pints the giraffe let out a huge long throated sigh, well it would wouldn't it, and collapsed on the floor in a very long heap.
The bloke jumped to his feet and got quite angry and started shouting at the giraffe and then said sod it that was the last time he was going to take the dammed thing out boozing and started to walk out of the pub!
The landlord leaped out from behind the bar and asked the bloke where he was going? The bloke replied that he was sick and tired of the thing and he was going home!
The landlord said "No! You can't go and leave that lyin there!"
The bloke looked at him with a curious look and said "That's not a lion, it's a giraffe" and walked out.
