SNL stars Jost and Che perform an annual joke swap where they are forced to read jokes the other has written for them. But the recent segment went mega viral for capturing Johansson’s candid reaction to the several NSFW jokes Che wrote for Jost to say on the air. (You can watch the full segment below.)

Colin Jost says Scarlett Johansson was “genuinely so shocked” over the “vagina joke” on Saturday Night Live. Jost and his “Weekend Update” co-host Michael Che have made a joke swap tradition by writing jokes for each other.
