"The perfect pair" joke

The Queen and Dolly Parton die on the same day, and they both go before St. Peter to find out if they'll be admitted to heaven.
Unfortunately, there's only one space left that day, so St. Peter asks Dolly if there's some particular reason why she should go to heaven.
She takes off her top and says,
"Look at these. They're the most perfect ones God ever created, and I'm proud to own them."
St. Peter thanks Dolly, and asks the Queen the same question.
She then drops her skirt and panties, takes a bottle of Perrier out of her purse, shakes it up, and douches with it.
St. Peter says, "OK, Your Majesty, you may go in."
Dolly is outraged. She screams,
"What was that all about? I show you two of God's own creations, she performs a disgusting hygiene
act, and gets in, and I don't?!!!"
"Sorry, Dolly," says St. Peter,
"But a royal flush beats a pair any day."
