A man goes to the doctor and gets told that he only has a week to live. He is told has a very very rare kind of cancer called Yellow 257.
He goes home and decides to spend his last week doing things he'd always wanted to do but never had the time. That night he goes to bingo for the first time in his life. He buys only buys strip of a book, yet he goes on to win every single line and every house all night!
The bingo caller approaches him on his way out and he says, "I've been calling bingo for 20 years, and never ever have i once seen one player win every line and every house all night. You are quite possibly the luckiest bastard I have ever met!"
The man replies, "Me!? Lucky!? You've gotta be joking! I'll let you know I've got Yellow 257!!
"Fucking hell, you've won the raffle aswell!!" replies the caller!
