If you've fallen a little out of love with Lip Sync Battle [1] lately, you're definitely going to want to tune in on Thursday. The adorable kids of Stranger Things [2] are going head to head, and it already looks amazing. Not only does Finn Wolfhard [3] go retro (complete with Stranger Things [4]-inspired Christmas lights and alphabet wallpaper) for Weezer's "Buddy Holly," but Caleb McLaughlin even channels host LL Cool J as he busts the rhymes to "I'm Bad" on stage. These kids are just too cool for their own good.
