A Conundrum, With Parentheses

This evening, Brian knots up a silk tie narrowly striped with the colors of champagne and caviar. Oddly, he paired it with a shirt of palest blue. Qu'est que c'est? Has Brian been watching Stacy and Clinton, and mistakenly thinks that the shirt is "popping" this ensemble? Did he have an unfortunate incident with his Usual White Shirt and have to go to the Emergency Shirt hanging in the NBC Newsroom? Or, did he perhaps have a Catastrophe du Cravate and have to go to the BackupTie? You know, the One Which Goes With Everything (Well, Almost)? Ah, the dreaded Parenthetical Exception strikes again.
