A man runs into a pub and orders the three most expensive malt whiskys they have. The barman lines them up, but before he's finished pouring the third, the bloke downs the first in one.

As he necks the second, the barman says to him, "You're in a hurry." The bloke replies, "you would be too if you had what i have." The barman says, "Oh sorry, what to hear that mate, what have you got?" The bloke downs the final whisky and replies, "50p."
