Bloke rushes into a bar.
"Quick! Give me a pint of bitter!"
The barman hurriedly gives him a pint and the man wolfs it down in seconds.
"Another!" shouts, the man and the barman complies. The guy drinks this just as fast as the first.
"Another!"
This goes on until the guy has drunk 10 pints in very quick succession, and whilst the 11th pint is being poured, the barman says, "why are you in such a hurry?"
The drinker replies with a sad face, "if you'd got what I've got, ....you'd be in a hurry!"
Concerned, the barman says, " wh-wh- what have you got?"
The man replies, "50 pence".
