To Catch a Thief, Part 1

Jeff noticed a ring on the floor close to his workstation, but after conferring with Les, he chalked it up as a clumsy accident. However, his suspicions were heighened when he found some scrap jewelry on the floor, leading to he and Les to conclude that an American Jewelry employee is a thief. After a check on the security cameras yielded nothing due to technical problems, Jeff decides to create a sting operation as a way to catch the thief in the act. Also: an unruly customer threatens Les with death, resulting in a call to the Detroit Police Department when security found him too tough to handle. And Seth wonders if they can sell a pair of size 21 sneakers worn by Shaquille O'Neal, which are taking up a lot of space on the sports shelf -- along with some sports jerseys.
