This edition was ranked joint 11th in the TV chart along with three other programmes. The Fall of the House of Unsworth (1980), Episode #1.3389 (1980) and Frankie Howerd Reveals All (1980) all received viewing figures of 14.85 million, the same as Blankety Blank.
A lot of the humour for Blankety Blank comes from the questions being able to be misinterpreted as innuendo. This is an unusual episode in that none of the questions could be regarded as having an explicit double meaning.
