This comic reminds me a lot of the scene in Harry Potter and the Half-Blood Prince in which Harry pretends to spike Ron’s pumpkin juice with felix felicis, and Ron goes on to play a spectacular Quidditch match.
Moral of the story: you don’t need to resort to drastic measures if you believe in yourself.
Secondary moral of the story: Satan evidently has a good, wholesome twin brother, so be careful who you try to sell your soul to.
