The other day I watched a very informative and interesting documentary called "The Amazing Story of Superman" on the History Channel, which depicted the character in all mediums from the begining up to Superman Returns.
In it though, they showed quite a bit of ridiculously hilarious and stupid stuff such as the "Superman" musical TV special, and the unaired pilot of George Reeves' "Superman" spinoff "The Adventures of SuperPup".
One of the things I just found stupid was a part from the "Super Friends", that I just had to show you guys. People wonder why Superman started looking stupid as hell...
BTW, at the 5 second mark, Batman gives the greatest "WTF" face I have seen in a long time.
