I\'m sorry. I\'ll explain a few things..
Yes, it\'s a joke. Supreme (during Alan Moore\'s fantastic run) is partly a pastiche of 1960\'s comic books. Wacky plots, "Superman is a dick" style covers, and retarded public service announcements.
If you read comics or have any knowledge of their history, this is pretty funny. Otherwise, I can understand the groaning. Heh.
That "ad" was made in, like, 1997 or 1998.
