Infamous crank phone-callers Johnny G. Brennan and Kamal Ahmed, better known as the Jerky Boys, unknowingly pranked 22-year-old videostore employee Jake Matson, their last remaining fan, Tuesday. 'Hello, this is Frank Rizzo,' said Brennan. 'I'm throwing a bachelor party and I wanna come over there and rent some smutty animal videos. What kind you got there, sizzle-chest?' Matson, who, unlike his peers, still listens to his Jerky Boys CDs regularly, instantly recognized Brennan's voice and begged him to do a few seconds of Saul Rosenberg.
