What are some of the silliest moments from the Silver Age of Comics?
I think one of the best ones (as in one that made me laugh out loud when I read it) was when the Avengers first encounter Zemo and his Masters of Evil in Avengers #6. We're treated to a hilarious flashback where Zemo had Adhesive X poured on him, resulting in his mask getting glued to his face. As if that wasn't funny enough, during the 20 years he had it stuck he never thought to look for a solution until someone else mentioned it offhand.
Zemo: A solution to Adhesive X! I never thought of that!
