At the end of his show on Sunday, John Oliver proclaimed that the only thing likable about Mike Pence is the fact that he has a bunny rabbit named "Marlon Bundo". Pence's family published a kid's book about Bundo and life in the White House, which was released today, the 19th.
So Oliver announced that he was publishing a kid's book about gay bunnies getting married while an evil stinkbug who looks oddly like Pence tries to stop them. He published it on Amazon during his show, late on the 18th.
As of right now, John Oliver's book about gay bunnies is currently the #1 BESTSELLING BOOK ON AMAZON, while Pence's book isn't even in the top 10.
A+ level trolling.
