Butt-Monkey: When Barry comes into his life, his following days turn into a nightmare; he unintentionally breaks his back, gets him in trouble for accidentally giving his ex-girlfriend his address and mistakes Julie for said ex, embarrasses him at a brunch with his boss' client, and has his car totaled by his ex who posed as his current girlfriend! This guy just couldn't catch a break.
The Every Man: Aside from bringing in a few more figures than your average American, Tim Conrad is pretty much your typical Paul Rudd Straight Man.
Honest Corporate Executive: The biggest clash he has with the higher-ups is their obvious lack of morality. Tim is much more direct and honest, and lands a meeting with Martin Mueller by being just that.
Jerk with a Heart of Gold: Tim agrees to participate in the "Dinner for Winners" so that he can get a promotion and impress his girlfriend. He's clearly uncomfortable with it, and by the movie's end, he admits to his jerkassery.
Astonishingly Appropriate Appearance: A man who makes dioramas of stuffed mice and actually looks a little like a mouse himself- brown hair, prominent nose, prominent upper teeth.
Cloud Cuckoo Lander: Barry is a very, very, very large moron. That's the joke.
Cuckold: His wife left him for his callous boss Therman, and Therman doesn't hesitate to torment him with this.
Literal-Minded: Takes everything at face value or hilariously misconstrues the degree to which his help is required in a given situation.
Nice Guy: Though he causes nothing but misfortune for Tim the moment he steps into his life, Barry genuinely has his heart in the right place.
Julie
Portrayed by Stéphanie Szostak
Betty and Veronica: The Archie, to Tim's Betty (been her boyfriend for a long time, normal, wants to marry her), and Kieran's Veronica (just met her, eccentric, mainly interested in her as a paramour).
Mistaken for Cheating: First, she believed that Tim was cheating on her (no thanks to Barry mistaking her for Darla). Then Tim believed Julie was cheating on him with Kieran.
Satellite Character: Her character doesn't give much to the story but being Tim's long-time girlfriend.
