A man walks into a bar...

...and immediately a third of him leaves.

Two others come in, one vomits at the sight and leaves immediately while the other passes out.

The barman scoops up the mess and the guy passed out, and throws them both into a giant blender.

You've been sat, horribly drunk, watching all this happen.

The bartender pours you a glass of frothing red liquid from the blender. What do you tell him?

A: *I really don't want an other drink*

^(I don't like this either but it was in my head and I had to tell it.)

Edit: The remaining two-thirds of a man is "an", and one of the "others" is "other". They were made into a drink. an other drink.

Additional: You're drunk. Perhaps you're hallucinating. You don't want another drink.
