DC Comics published 24 issues of "The New Magazine of Weird Humor!" beginning with Plop! #1 (Sept./Oct. 1973). Because of the series three biblically named hosts (Cain, Abel & Eve; who always tried to one-up each other), Plop! is primarily considered a humor/horror anthology-hybrid. The first nineteen covers were provided by Basil Wolverton and Wally Wood, so you can see how it might earn that attribution.
Mad magazines Sergio Aragones, provided much of the framing sequence artwork and many of the books peculiar humor stories during the run of the series which ended in 1976. Plop! won the 1973 Shazam Award for Best Humor Story for "The Gourmet" in its first issue and a second nomination for another tale from the debut issue. Writer Steve Skeates also won a Best Writer (Humor Division) for his work on the series.
I remember my brother having a few issues of this title when we were kids, but nothing much else. Still, if you need to satisfy a yearning for some macabre humor or just plain weirdness, a back issue of Plop! would fit the bill. I've included a page of Aragones art as an example of what you could find within its covers.
