"Ready, Willing, and Disabled"
Season 3, Episode 15

It turns out, Evil Monkey is evil for a reason. He tirelessly slaved away at his soul-deadening corporate job, only to walk in on his wife cheating on him with another monkey. If there's any consolation to the night that he turned evil, it's that he was wearing a green suit that is reminiscent of the Kenzo number Robert Pattinson was seen rocking last year. Very trendy, evil monkey. Very trendy, indeed.
