[14] More a vehicle for his brand of humour than a genuine gameshow, Sticky Moments was a light-hearted "non-quiz" satire, with him often awarding points because he liked the contestants, rather than because they possessed a particular skill or aptitude.

In the episode "A Dream of Dracula", he played an undertaker, alongside other guest stars including Alfred Marks, Jill Gascoine, Ronald Fraser and Peggy Mount.

[16][17][18] Although the joke was met with uproarious laughter from the audience and Lamont himself did not complain over it, he was criticised in some newspapers, particularly by the Daily Mail and The Sun, who both launched a campaign to have him banned from television.
