Can’t Believe He’s Gone

A game invented by a brother and sister on December 25th 2016. It was a long holiday week of drinking. To hear the sister tell it, when news of George Michael’s death broke that evening, the brother was seen crying into his Christmas roast, repeating the phrase “can’t believe he’s gone”.

In its current form, the game consists of racing to inform the other first when a mutually-important celebrity dies.

There’s been talk of a point system, but one hasn’t yet materialized.

AP: This just in, Pope Francis has died of unknown causes.

Text: Can’t believe he’s gone!

Reply: Who? I didn’t see anything. Oh now I do. That’s a big one.
