There's a long tradition of parodies of title sequences, particularly those from US shows of the 80s and 90s. They are, after all, relatively easy, cheesy targets. And at least they had title sequences in those days, unlike a lot of network shows, which would rather save their ad-glutted hour-long time slots for the show itself.
However, I don't think there's quite been a title sequence parody the likes of Too Many Cooks. Adult Swim aired this at 4am early morning for a week last month, meshed in between infomercials, before anyone noticed it. The creation of writer Chris Kelly (Squidbillies and Your Pretty Face Is Going to Hell), it starts off as just a regular parody of the likes of Full House and Growing Pains, before becoming something altogether very different, alternately disturbing and comical.
I'm not sure how funny it is, but you won't have seen anything quite like it before, I guarantee.
