Mental_floss has a list of the 5 weirdest patron saints - for example:
Saint Drogo (1105-1185), a Flemish nobleman who was reportedly able to bilocate, maintaining his presence in two locations at once. Witnesses claimed seeing Drogo working in fields simultaneously, and going to mass every Sunday. He is the patron saint of coffee and coffeehouses, we suspect because his peculiar talent for multitasking. (He’s also the patron saint of those whom others find unspeakably repulsive, but that’s another story altogether.)
