This character featured in The Beezer comic in the late '70s / early '80s, an obnoxious child who was much addicted to practical jokes of a not very pleasant sort. He was a kind of equivalent to The Beano's 'Roger The Dodger', but of a less pleasant nature- whereas Roger's only aim was to get out of doing things that he didn't want to have to do, Dicky just played pranks on the innocent and unsuspecting just for the hell of it. Needless to say, he usually got his come-uppance at the end of each story.
He's worth singling out for a mention because his face was not at all dissimilar to that of disgraced US President Richard Nixon, who's nickame was also 'Tricky Dicky'. Could the latter have inspired the former?!
