SCHAUMBURG, IL—Tragedy struck an otherwise ideal love affair between Frank Langford, 31, and Amy Diamond, 28, Monday, when Diamond used the toilet directly in front of her beloved for the first time. "Deep down, I knew this awful development was inevitable, but it still hurts to see the black day finally come," Langford said. "The most crushing part is that I didn't even mind that much. After all, I stopped bothering to suck in my gut around her months ago." Although it only began two years ago, the couple's relationship has already experienced such cataclysmic events as the no-longer-hiding-morning-breath stage and the slapping-each-other-on-the-ass-in-an-entirely-nonsexual- manner stage, and is now rapidly approaching the final indignity of the actual-love-based-on-mutual-understanding- and-respect stage.
