I always loved the name of Screaming Yellow Zonkers.
They were sort of like Cracker Jack and their original box back in the 70s was hilarious (“Easily cheaper than diamonds of equal weight.”) The same company also makes Fiddle Faddle and Poppycock (which, if you know the etymology of the term*, is a terrible name for snack food).
Here in Newark, DE, there is a heavy equipment rental place called “Hire-a-Hoe”. And it’s right next to a church! Been there for years and it still gives me a laugh.
In San Diego there is a funeral home called Goodbody Mortuary. It’s probably someone’s last name, but still they must have had quite a sense of humor to name the funeral home that.
Not really clever, but there is a surfboard wax called Sticky Bumps. Sounds like a social disease to me.
