Perhaps you've heard of Hulu - the web site that let's you watch studio cast-offs like Nanny and the Professor from the low-tech inconvenience of you're own laptop.
Now there is a thing called Hulu Desktop which adds a completely unnecessary application layer to the mix. I'm not sure what the benefit of running Hulu as a program instead of a web page gives me, but it supports Mac - hence the recommendation.
(Actually, Hulu has a lot of great shows like 24, Arrested Development, and a few other complete series I wasted perfectly good money collecting on DVD.)
It occurs to me that if Nanny and the Professor were on today, it would probably be called Tranny and the Professor - and be cancelled after two weeks on FOX.
