However, there's no mention of characters named Wendy Wildcat Cousin Delightful or Stupefyin' Jones in the original "Li'l Abner" comic strip or any known adaptations.
It's possible you're thinking of a different comic strip or a parody of "Li'l Abner."
Could you provide more context or information about where you encountered these characters? Perhaps you have the wrong names, or there's a different source for your information.
