During the events of Airwolf: Season 2 Episode 20 Severance Pay played by Arte Johnson
Larry is watching a Soviet report on Airwolf, which Libya claimed to have destroyed. Members of the FIRM, including Joe Kline, walk in to his office singing For He's a Jolly Good Fellow. Larry tells Joe he thinks the Soviets know information about Airwolf sooner than they should and watches another report on Airwolf. After work, Larry goes up to Arthur Barnes and gives him reports on Airwolf. At Santini Air, Larry walks in and invites Stringfellow Hawke and Dominic to the bar after telling them he and Joe bought a coffee barge in Mexico. Larry tells them he thinks there is a mole and the Soviets know about Airwolf and the missions it goes on. At Records and Grievences, Larry and Joe argue with the Records Clerk who tells them they are listed as temporary workers according to the computer files and not eligible for retirement bonuses. Joe demands his bonus check and then has a heart attack and dies. Later, Larry walks back into the Records and Grievances Department and places a makeshift bomb which goes off and destroys some records. Larry calls the FIRM and demands the bonus check he and Joe deserve or he will reveal information to the press. Arthur tells Larry he will personally check into his grievance if Larry turns himself in, but Larry demands his money. He hacks into the FIRM database and steals classified information. Larry, dressed as a Parks and Recreation Department worker, tells Hawke he took classified information and Hawke asks him to talk with Archangel. They get into Larry's van, but are tailed by Henderson. Larry and Hawke manage to get away when Larry sets a trap for Henderson outside of a police station. Larry tells Hawke to get out of his van and leaves him on the side of the road. Larry sees a report by Carling on the murder of two agents and calls Hawke and tells him he didn't provide the information. Larry is told by phone to go to Los Hermanos airstrip in Mexico. Michael Coldsmith Briggs III, Archangel and Marella pick up Larry and are flying him back to the FIRM when a plane starts to fire at them. Hawke and Dominic in Airwolf shoot down the plane. The FIRM committee holds another meeting and Zeus tells Arthur plane wreckage was found along the Gulf and they suspect Archangel, Marella and Larry are dead. Zeus commends Arthur for catching and killing Henderson, but then asks Arthur why a pilot was hired by a Soviet agent in Mexico. Archangel and the others walk in and Arthur is taken away to be killed. Marella and Archangel tell Larry that he and Joe's wife will be getting the bonus he and Joe earned and Larry is flown to Mexico in Airwolf.
