No, folks, you're not seein' double (five times!) DC's 1969 comic book series The Way-Out World of Windy and Willy (four issues plus a debut in Showcase) was inspired by DC's own '60-'64 series The Many Loves of Dobie Gillis...inspired by, in this case, meaning very nearly the same comic book! Each of the Windy stories was a reprint of a Dobie story, relettered and retouched to reflect the changed character names and designs, with newly drawn covers using the same old jokes as five issues of Dobie by the original artist, Bob Oksner! So, which DC-Earth do you think Dobie lived on...and did Willy live on its version of Earth-2? Now that there's only fifty-two earths, are they both stuck on Earth-28, the home in the multiverse of Alan Ladd, Dean Martin and Jerry Lewis, Pat Boone, Bob Hope, and Puffy AmiYumi? And if so, when will they cross over with Superman and Batman and Wonder Woman?
Call me, Didio. I've got the whole 12-part megaseries worked out in my head already.
EDIT!: Hold the phone, Separatists! We've got ourselves a triplet!:

Brought to my attention by "Dauntless" Dr. K of Dr. K's 100-Page Super Spectacular, here's a third version of the beach gag shown above on Dobie #3 and Windy #2. The evidence mounts for an analysis of Hodgkin's Law of Parallel Planetary Development to be applied to the pre-Crisis Earth-28: in a world where three pairs of teenagers make the same jokes in the period of twelve years, surely there's some giant hand at the beginning of time spinning events into some sort of multiple-earth beach-gag tapesty!
Or, maybe, like everybody imitating the Fonz or Austin Powers, it's just an old joke used one time too many. Only Rip Hunter, Time Master could tell us for sure!
Thanks, Dr. K!
