Do you remember the episode of Regular Show, The Best Burger in the World? I think it was the worst episode of the series overall. It comes off as unsatisfactory, disgusting, and rage-inducing because of Benson's abusive treatment towards Mordecai and Rigby.
Well, in case you didn't know, there's a fanfiction that takes place after the episode and Benson receives his well-deserved karma. You can view the story here.
