Queen Elizabeth and Dolly Parton die on the same day and they both go before the angel to find out if they'll be admitted to heaven. Unfortunately, there's only one space left that day, so the angel must decide which of them gets in.
The angel asks Dolly if there's a particular reason why she should go to heaven, whereupon she takes off her top and says, "Look at these, they're the most perfect breasts God ever created, and I'm sure it will please God to be able to see them every day, for eternity."
The angel thanks Dolly and asks Her Majesty the same question. The Queen takes a bottle of Perrier out of her purse, shakes it up, and gargles. Then she spits into the toilet and pulls the lever.
The angel says, "OK, your Majesty, you may go in."
Dolly is outraged and asks, "What was that all about? I show you two of God's own perfect creations, and you turn me down. She simply gargles and she gets in. Would you explain that to me?"
"Sorry, Dolly," says the angel, "but even in heaven, a royal flush beats a pair, no matter how big they are."
