McFingers once sponsors Barney Stockman (Baxter's twin brother) to create a "gag-a-magnifier" device that increases the comedy power of jokes. They planned to hook up the funniest comedian to it and transmit the joke waves all over the city, making everyone hysterically helpless; meanwhile, McFingers and his two goons would go out and rob the city. He and his men kidnapped comedians until they kidnapped Raphael. They tied Raphael up in a sack and took him to their hideout, where strapped down, McFingers tells him of his brilliant plan. Being the funniest comedian, Raphael is forced to start telling his jokes. However the rest of the turtles rescue him and the other comedians and turn the devise against Stockman and the McFingers gang, all of whom end up arrested.
