Ever since Dec. 2018, Saturday Night Live Weekend Update anchors Colin Jost and Michael Che have celebrated Christmas with a new tradition. The two swap jokes live on-air, reading jokes their co-anchor has written that they’ve never seen until now.

Basically, it’s an excuse for Jost and Che to make the other say some wildly offensive things, and to end the year, the pair reach new heights. Nothing is off the table, from slavery reparations to allegations against rappers Sean “Diddy” Combs and Jay-Z. But Che takes things to a nuclear level by making Jost joke about his marriage to Scarlett Johansson (Fly Me to the Moon) while she’s in the studio.

That’s right: Johansson, who made a cameo in the episode’s Five-Timers Club cold open, was watching live. And SNL made sure to catch all her reactions to Jost’s jokes from Che. You just have to see it to believe it.
