A scene based on a conversation between two old friends of mine- Emily, a goth girl, and Dennis, an old school rock and roller- set in bed, about 22 or 23 years ago :

Emily: So....When's your birthday?

Dennis: The eighth of January, the same day as The King of Rock and Roll.

Emily: Elvis? Ugh. He sucks. It would be much cooler if you had the same birthday as David Bowie.

Dennis: The eighth of January is Bowie's birthday, too.

Emily: [surprised] Oh! [inner dialogue] I'm going to have to marry this guy!

And they wed shortly thereafter. And that's why I always remember Dennis', Elvis' and David's birthday every year.
