Stop me if you've heard this one before...
A zoo keeper and a giraffe walk into a bar.
They order and consume many many drinks.
Eventually the giraffe passes out on the floor, completely drunk.
The zoo keeper settles the bill and heads towards the exit.
Bar tender shouts, "Hey! You can't leave that lying there!"
Zoo keeper turns, "That's not a lion. That's a giraffe."
So I'm thinking of submitting this to Theodore's Pixel Challenge.
