Superman moments in Seinfeld the TV show. A couple you just have to look around and see the Superman items in the background and then there's a few really good Superman jokes in there. Of course they put some of the Superman Seinfeld commercial moments in there for good measure.
I thought they were kinda dumb but then again I don't like Jerry Seinfeld. Plus the guy who voices Superman I think is the same guy who is Joe Swanson on Family Guy I could be wrong.
