Ed the Happy Clown is a graphic novel by Canadian cartoonist Chester Brown. Its title character is a large-headed, childlike children's clown who undergoes one horrifying affliction after another. The story is a dark, humorous mix of genres and features scatological humour, sex, body horror, extreme graphic violence, and blasphemous religious imagery. Central to the plot are a man who cannot stop defecating; the head of a miniature, other-dimensional Ronald Reagan attached to the head of Ed's penis; and a female vampire who seeks revenge on her adulterous lover who had murdered her to escape his sins.

Ed spans a range of Brown's interests, from political skepticism to scatological humour to vampires and werewolves. The story is dark and surreal, desperate and humorous.  Christian elements especially--largely sacriligeous--are prominent in the book. They are at first innocuous and unimportant: a zombie named Christian, another character who believes he has found Christ's face on a piece of adhesive tape. With the fourth issue of Yummy Fur, Brown's surreal take on Christianity becomes central: the cover depicts the Virgin Mary holding not just the infant Christ, but also a severed hand. Within is the story of Saint Justin, whose amputation becomes a key motif: Chet loses his own hand and finds another; his own appears mysteriously under Ed's pillow. Only by praying for forgiveness for his adultery and by murdering his lover is Chet's hand miraculously restored. According to the Lives of the Saints, the fictional Saint Justin severed his own hand, but in another version Brown presents, Justin's wife cuts it off with a woodaxe when she catches her husband masturbating after rejecting her advances. Despite Saint Justin's story's exposure to the reader as a fraud, Chet's faith in the official version restores his severed hand. The altered ending from 1992 has both Josie and Chet reunited in Hell, and the ghost of Chet's sister becomes a devil. As Brown mixes surreal sacrilege with the sort of moralism that compels him to condemn Josie for her bloody revenge, Brian Evenson calls Brown "deft at muddying the waters in a way that makes it very hard to pin him down as either belieever or satirist, as either anti-religionist or apologist".  While not part of the Ed story, Brown had been serializing straight adaptations in Yummy Fur of the Gospels of Mark and of Matthew during most of Ed's run. R. Fiore called these adaptations "the best exploration of Christian mythology since Justin Green's Binky Brown", comparing Chet's excessive Christian guilt with the "almost childlike retelling" of Mark. Yummy Fur readers also found "I Live in the Bottomless Pit", a short strip in which a man discovers the Antichrist, who after millennia underground has forgotten his mission--a paradoxical one, as he states his orders were from God.  Ed prominently features transgressive content including nudity, graphic violence, racist imagery, blasphemy, and profanity. Brown grew up in a strictly Baptist household in which he was not allowed to swear, as depicted in Brown's graphic novel I Never Liked You (1994). Brown challenged his own anxieties by tackling subjects such as scatological humour. Imagery such as the recurring Pygmy characters and their "ooga booga" language, Chris Lanier asserted, reinforce "old colonial imaging of 'third world natives' ".Answer this question using a quote from the following article:
