Bi-monthly humor anthology series with a few semi-horror stories mixed in. Editor Joe Orlando was the man responsible for DC's 1970's horror-mystery titles and tried his hand at humor with a bit of the macabre thrown in.
In the planning stages, the series went through a few title changes from "Black Humor" to "Weird Humor" to "Zany" and then finally the title, "Plop!" was suggested by then DC publisher, Carmine Infantino.
