While Dwight settles for a job at Staples, Andy tests the last nerve of his coworkers, particularly Michael and new deskmate Jim, to whom he shows off his cell phone ringtone that he sang himself.

Jim tries to enlist Karen's help in pulling a prank on Andy, but she is busy with Dwight's former clients. Pam, however, is a ready accomplice. With her help, Jim hides Andy's cell phone in the ceiling above Andy's desk. Michael's rejection of Andy's friendship, combined with Pam and Jim's prank of continually calling his "lost" phone, pushes Andy over the edge, and he punches a hole in the wall in frustration.
