Eddie and Richie's money forging enterprise causes them to run afoul of local hard man, "Skullcrusher" Henderson.
Eddie reveals that his plan is to make sure people are so shocked by the perverse images that they will never notice how unconvincing the forgeries are.
The plan initially seems to work, but when Dick retreats to the backroom to "take a closer look," he phones his friend "Skullcrusher" Henderson, the biggest forger in London.
The group, suddenly realising why he is called the Skullcrusher, initially panics, before they discover that the pub has its annual quiz that evening, with a £5,000 prize.
Eddie takes a rather more proactive approach and sabotages the other team's buzzers to administer near-lethal electric shocks when pressed.
