Probably the sole heartwarming moment in this movie: Tom tries to kill himself after being fired, but seeing his wife gives him a new desire to live. And then he gets hit by a drunk driver, but hey, he lives! Albeit with multiple limbs broken, but at least he's got a nice, fat settlement!
After Peter accepts the consequences of his actions he admits to Joanna that even if he can't be happy with his job, he can be happy with his life as long as she's part of it. Awwww.
Peter trying to save the remains of the vaunted red Swingline in the post-fire salvage scene also arguably qualifies.
