Denton (Pemberton) and his wife Val (Gatiss) are a bizarre couple whose gaudy 1970s-style house is run in an insanely ordered manner. For examples, they have two rolls of toilet paper labelled "1's" and "2's," and colour-coded towels for every purpose, from hands and spills to pubic hair. They have identical twin daughters, Chloe and Radclyffe (played by twins Megan de Wolf and Rosy de Wolf respectively ) With their long white dresses and their habits of turning up unexpectedly and speaking in unison, they are obvious references to the two girls in The Shining. Harvey's dream in life is to have a self-lowering toilet seat. Val's wish is to have a son. Into this formula, their completely normal nephew Benjamin (Shearsmith) is interjected. Harvey and Val tell him to make himself at home which is obviously impossible. Harvey is obsessed with male masturbation, forever accusing Benjamin of masturbating, using an array of amusing euphemisms. Harvey is deeply fascinated by toads and has had the basement converted into a special chamber for keeping his huge collection. He is not so fond of frogs, refusing to allow the use of "The "F" word" in his home. He also owns the toad known to the Mapapa tribe of the Shakiti Hills as the devil's toad. "If one were to squeeze its little yellow belly, one's heart's desire would be granted." With him and his wife, Val, that turned out to be true. He wished for a self-lowering toilet seat, while Val asked for her nephew, Benjamin, to return. Both wishes come true. Benjamin also made the mistake of killing two of Harvey's favourite toads, Sonny and Cher (named after the musical duo), by frying one on an electric heater and stepping on the other. The Dentons also have a "nude day," which they claim is the first Monday of every month. They cast aside all clothing and go about their daily duties—including going to the supermarket, the newsagents, and the post office, totally naked. When Benjamin walks in on them naked, they force him to strip off as well and answer the door naked. Benjamin surprises the caller and brings him back to the living room, where Harvey and Val are dressed, and Benjamin is humiliated. As Series 1 progresses, it becomes clear that the pair, especially Val (whose greatest wish is to have a son), do not want Benjamin to leave.
