A man goes to the doctor's, feeling a little ill.

The doctor checks him over and says, 'Sorry, I have some bad news. You have Yellow 24, a really nasty virus."
"It's called Yellow 24 because it turns your blood yellow and you usually only have 24 hours to live"
"There's no known cure, so just go home and enjoy your final precious moments on earth.'

So he trudges home to his wife and breaks the news.
Distraught, she asks him to go to the bingo with her that evening as he's never been there with her before.

They arrive at the bingo and, with his first card, he gets four corners and Wins £35.
Then, with the same card, he gets a line and wins £320.
Then he gets the full house and wins £1000.
Then the National Grid comes up and he wins that too, getting £380,000.

The bingo caller gets him up on stage and says;
'Son, I've been here 20 years and I've never seen anyone win four corners,
a line, the full house and the national grid on the same card.
You must be the luckiest man on Earth!

'Lucky?' he screamed.
'Lucky? I'll have you know I've got Yellow 24.

'Stuff me,' says the bingo caller. 'You've won the raffle as well!'
