Hang on. . . let me get this straight. . . I assume you were sitting, right? So you're sitting there, flourishing (or whatever), and the cards happen to fall. How exactly, with you seated on the toilet, do the cards manage to fall into the toilet? Maybe I'm weird, but I usually situate myself in such a way that if I were to practice cards on the commode (which I never have), I don't think they'd be able to find a direct bath into the bowl, regardless of how I dropped them.
