This week during The Tonight Show starring Jimmy Fallon, host Fallon invited Millie Bobby Brown (Stranger Things) to play a new virtual version of “The Whisper Challenge!”

The premise is simple. Mute your sound, then guess what the other person is singing by reading their lips.

Watch the video below:

Jimmy and Millie Bobby Brown attempt a social distancing version of the whisper challenge, where they take turns guessing the titles of random songs they’re singing while muted over video chat.
