With Arthur's dodgy schemes, the duo encounter undesirable underworld figures, many of whom Arthur deals with and many of whom turn nasty, leaving Terry to fight and outwit their way out of trouble. But for all Arthur's obsession with get-rich-quick schemes, he is never malicious, usually simply being blinded by greed, and the pair often end up putting some other wrong right or helping others in need or who have been done wrong by, even if it proves to be Arthurs's Achilles' heel to his latest scheme fully succeeding. Most of Arthur's schemes fail in the end, owing to his greediness, but he does occasionally have the odd minor victory and puts one over on the law or more serious criminals.
