Actually the Coriolis effect is so small with respect to other forces acting on a flushing toilet or a draining bath that it effectively has no effect at all. The direction in which a toilet or bath vortex rotates will be determined by the local forces acting on the water. And I'm pretty certain the writers of the Simpsons would have known this.
Reason: the Earth's rotation is so slow, that for the Coriolis effect to have any noticeable impact on a rotating fluid, it needs to be big - very big, on the scale of large weather systems and atmospheric and ocean currents.
