What metaphors are used in Naked Pictures of Famous People by Jon Stewart?

Despite its suggestive title, sex plays a minor role in Jon Stewart's Naked Pictures of Famous People. It is lustily intimated in the opening story, "Breakfast at Kennedy's," where toddler Edward (Teddy) takes a young girlfriend on a tricycle ride near the water from which she does not return, and in "Lack of Power: the Ford Tapes," where the new President Gerald Ford guiltily ogles a copy of his predecessor's Playboy magazine, and first comes on full-force in "Martha Stewart's Vagina."
