Ken Levine's blog, if you don't have it bookmarked yet, is a great read for those of us who love classic television comedy (and radio!). Ken was a disc jockey and sportscaster, but he was also one of the all-time best sitcom writers. In this blog post from Friday, he examines the innacuraccies of WKRP in Cincinnati (one of my favorite shows).
Many of his observations here also hold true for "Frasier", by the way, which Ken wrote for several years.
