In each edition of the LangaList, Fred Langa includes a “Just for Grins” entry. The latest was a link to an American Express advertisement site. It's a series of “ad-ventures” starring Jerry Seineld and Superman.
Need I say much more?
I found the Flash version somewhat lacking and clicked the “Trouble with Flash? Go to HTML.” link that gave the option for either Quicktime or Windows Media versions of the clips.
Very funny. As good or better than Super Bowl ads.
