Later, in the warehouse, Dwight is mocking the concept of a slack line while dismantling a bicycle and a folding table, to be recombined into some misbegotten hybrid of the two.
In the kitchen, Pam gets a text from Dwight, apparently summoning her to the stairwell where the ladder to the roof is. There she finds a cable attached to one of the rungs, stretched tight as a guitar string (which she plucks in demonstration), and Dwight on the roof wearing a helmet. She emerges onto the roof to find him with some kind of jury-rigged bicycle-on-a-tightrope setup.
Angela is interviewing Pete, even though he doesn't want the damn cat anyway. Jim listens in on Pete's ambitions, which Pete has been putting off in favor of fitting in around the office. Jim looks all superior and THs, "If he doesn't watch himself, he's going to be here for years. Doing nothing." And then the penny drops. "Wow, maybe Pete is the new Jim." Well, yeah, we got that.
Dwight explains to Pam what he wants from her: to sit on the swing duct-taped beneath his bicycle while he pedals across the tightrope to the telephone pole on the corner. Pam is not having it, even with this week's theme of how boring her and Jim's lives are. She suggests Phyllis instead. "The moment she steps off this bar I'd be launched into space!" Dwight protests. "God, you're so insensitive!"
Overhearing Angela tell Pete that the baby is allergic to Comstock, and that her husband is so upset about it he cried for the first time since their wedding night, Oscar at last agrees to take the cat. Angela's happy, except for how Robert won't get to say goodbye because he'll be at a business dinner. Cut to Oscar on his cell phone in the stairwell, saying, "Tonight when you come over for dinner, you can play with your old buddy Comstock." And then he ducks out of sight when he sees Pam coming down the ladder from the roof. So that's actually happening? Clearly Angela's husband is an idiot, shitting where his wife eats.
At 5:01, everyone's heading out for the day. Jim sends Pam on ahead so he can "make a call." Up on the roof, Dwight finishes duct-taping a printer under his wire-bike to serve as a counterweight, looks over the edge, and takes a deep breath. Down at his desk, Jim takes a deep breath of his own and dials, then hangs up quickly. He gets up to leave, but goes back to the phone again, like me when I used to work up the nerve to call this girl in high school. Yeah, it was our 21st anniversary last week, thanks very much.
