In some episodes, a guest character was essential to the plot. Del's ex-fiancée Pauline (Jill Baker) dominated Del's libido in "The Second Time Around", prompting Rodney and Grandad to leave. In "Who Wants to Be a Millionaire", Del's old business partner Jumbo Mills (Nick Stringer) wanted Del to return to Australia with him and restore their partnership, forcing Del to make a decision. An attempt by Lennox (Vas Blackwood) to rob a local supermarket set-up the "hostage" situation in "The Longest Night". Del and Rodney spent the whole of "Tea for Three" battling each other for the affections of Trigger's niece Lisa (Gerry Cowper), who briefly reappeared in "The Frog's Legacy". Abdul (Tony Anholt) in "To Hull and Back" and Arnie (Philip McGough) in "Chain Gang" were responsible for setting up dubious enterprises involving the Trotters in their respective episodes. Tony Angelino (Philip Pope), the singing dustman with a speech impediment, was the key to the humour and the storyline of "Stage Fright" and "EastEnders" actor Derek Martin guest starred in "Fatal Extraction".
