Name and Name

Well, The Noun and the Noun meets Character Title. Usually the title characters are either lovers or Heterosexual Life Partners. This is also a standard title form for Buddy Cop Shows. It's also the obvious choice for a Sketch Show starring a Double Act.

A variant, often found in slacker comedy films, is "Name and Name Do Stuff". (See also Episode Finishes the Title.)

If one of the names is mostly irrelevant, see Garfunkel.

See also The Noun and the Noun for titles of various works, and Magic Ampersand for game names.
