The name "Frank Spencer" may be used in the UK to refer to a particularly inept man, particularly one who is not very good at home improvements; "he did nothing right, and two things wrong". Examples of the phrase in ordinary usage are: "He's a bit of a Frank Spencer" or "Well that was very Frank Spencerish".
