I wasn't aware of this, but in an article titled "It's Only A Comic Book" by Clay Geerdes in the 27 Oct. 1972 issue of The Staff, he mentions that Laugh in the Dark is actually Bogeyman #4. Anyone else know this. I know that Tortoise and the Hare is Air Pirates #3, but didn't know this...
That's what I've read, though I'm not sure where.
I believe that bit of info came from Kennedy's guide. I've got it listed that way, too.
Here's an expired eBay auction that refers to it as Bogeyman #4: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=310056507682.
