I recently posted an article about the upcoming action figure series featuring Alfred E. Neuman as various DC superheroes, and there was a comment posted which stated something to the effect that MAD Magazine is dead, outdated and nobody cares.
I guess whoever wrote that hasn't watched Cartoon Network at all since September 2010, when the hilarious, and extremely popular, animated sketch comedy show MAD premiered.
MAD often features superhero themed sketches, including this segment which aired July 2011 and features an adorable Adventure Time and Avengers mashup, with the least muscle tone ever displayed on a superheroic character design.
Watch and laugh, because MAD is still cracking people up to this day, but it can only make you laugh if you're aware it actually exists.
