(S06E16)

Bart: Hey guys, just so you don't hear any wild rumors, I'm being indicted for fraud in Australia.

Homer: That's no reason to block the TV.

We get a rather dubious science lesson at the beginning of this episode when Lisa explains to Bart that the water in the sink and toilet always spins in the same direction due to the Coriolis effect. Usually the writers try to be scientifically accurate, but in this case they had to jump on the "water always flows one way in one hemisphere and the opposite direction in the other" bandwagon, or else Bart never would never have called Australia to see which way their toilet drains, and we wouldn't have ourselves one of those "Simpsons go abroad" episodes.
