Once again, 'American Dad' flew solo this week, representing the vast Seth MacFarlane Sunday night empire on FOX. 'Sons of Tucson' will be back to finish its run throughout the summer. The geniuses at FOX then decided that next week, 'Family Guy' and 'The Cleveland Show' will be all new, while 'Dad's' a rerun. This is the kind of brilliant planning that had 'Sons' premiering after a night of almost all repeats.

(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.
