The popular prank series returns for its fourth installment, targeting innocent apparel store clerks! We ask them to hem our pants and lure them into the fitting room. Complaining the waist is too tight—"it's like I'm getting a boner"—and pretending we can't determine the right size, we feign inability to purchase the pants. Seizing the moment, we ask, "Can you help me calm my erection down?" The clerks, blushing and hesitant at first, eventually give in and comply.
