Bingo.

A young girl from Donegal leaves home to find work in the bright lights of London. She comes home 6 months later and steps out of a taxi wearing a full-length mink coat. "Begorrah, Colleen," says her mother. "Tis a lovely soft coat yer wearin' an' it looks so expensive. Where did ye get
that?"

Colleen replies, "Sure now, I won it at the bingo. Don't they have wonderful prizes in London."

When the weekend's over, Colleen returns to the bright lights, but she's back to visit her mom a few months later. This time, when she steps out of the taxi, she's wearing a beautiful gold wristwatch and a large diamond ring.
Same exchange with Mom............same "Won it at bingo!"

Then Colleen returns to the bright lights again. A few months later, she's back again. And this time she's sporting a beautiful emerald diamond necklace with matching bracelet and earrings. She hands her mother 1,000 pounds and explains that she won it all in bingo. Then she
asks Mom to run her a bath as she need to freshen up.

Her Mom draws the bath while Colleen gets undressed in her bedroom, but when she gets to the washroom, there's only a quarter inch of hot water in the bathtub. Colleen, a wee bit peeved at her Mom being so cheap with the hot water after being handed 1,000 pounds, calls downstairs, "Mom!
Sure now didn't I ask you to run me a bath? There's only a quarter inch of water in the tub!"

"Indade there is, me darlin," replies her Mom. "We don't want ye gettin' yer bingo card wet now, do we."
