Bridget telling off Mark after the "Smug Married" dinner, this pushes him to start admitting the feelings he has been harboring for her and leads to a Crowning Moment of Heartwarming
Bridget: Look, are you and Cosmo in on this together? Because every time I see you, you seem to go out of your way to make me feel like a *complete* idiot. And you really needn't bother: I already feel like an idiot most of the time anyway - with or without the fireman's pole.
In the sequel to the novel, Shazzer tells off Cosmo and Woney, the Smug Married couple, for bugging Bridget about not being married and that her life isn't any less well-adjusted than theirs. She scares them off.
