Joss Whedon's story, "Some Steves," sees a comicbook fan from our world visit an interdimensional comic-con and discover other versions of himself whose lives weren't touched by Stan Lee's Marvel creations. It's less of a story and more of an excuse for Whedon to flex his comedic muscle, making the most of his chance to re-invent Stan's most inspired creations as less exciting, less fantastical comic books. The most successful gags come from these alternative takes on characters and storylines we know and love, and even if a couple of Whedon's other jokes fall a little flat - the "pornworld" thing might have been funny once, but suffers from the law of diminishing returns - it's not a bad hit rate for such a simple story (and all is forgiven for the inspired Snakes on a Plane visual gag).
