Three men rode into town on Monday. One of them was the
father of another one's son but all three were wearing different
coloured hats though none could see the colour of his own hat. One of
them always spoke the truth, one always lied and one (who did not have
a red hat) alternated between truth and lies.

Anyway, they walked into a bar and each put $10 on the bartop. The
barman, who was a perfect logician (though he had a curious habit of
never going abover floor 16 in an elevator) gave each of them $1 change
and kept $2 for himself.

The first man asked for a glass of water. The barman pulled a gun and
shot him through the heart. The man said 'Thankyou' then collapsed,
accidentally knocking over a nearby goldfish bowl in the process.

The second man had been playing with his 12 balls, one of which was
lighter or heavier, but now he asked for a whiskey on the rocks. He
took one sip and gasped 'This tastes of Albatross!!' before falling
down dead.

The third man was a one-armed surgeon who carried an alligator under
his arm. He stood on a block of ice and asked the barman, 'Do you serve
midgets?'
The barman replied,'Yes, we do.'
'OK then - make it a brandy for me and a midget for the alligator!'

Who was the liar?
