“Korg, the rock monster played by Taika Waititi himself, is one of the funniest characters in the movie, and introduces himself with a rock, paper, scissors joke when he first meets Thor.
But there’s more. At the end of the film, we see that Korg has accidentally crushed his blade-armed alien gladiator friend, thinking he killed him. Though the alien wakes up, the joke there probably sailed over everyone’s head. Rock beat scissors.
And if you want to go deeper than that, Korg explains to Thor how he tried to start a revolution but failed because he didn’t print enough pamphlets. Paper beat rock.
This is just too good. Too damn good, Waititi. Amazing.”
