Seinfeld isn't any worse than what most kids already watch. Compared to Family Guy, King of the Hill and other T.V. shows kids watch these days, Seinfeld isn't really that bad. Sure there is some inappropriate humor, but overall it's no worse than How I Met Your Mother and/or Friends. In my opinion if a parent thinks their child shouldn't watch it then block it. We have the technology! Anyway that is just my opinion, but of course everyone has their own views on how bad a show is or isn't.
