Who was The next door neighbor with pants up to his chest on the fresh prince of bel-air?

The next-door neighbor with pants up to his chest on "The Fresh Prince of Bel-Air" is Mr. Furley, portrayed by actor Don Knotts. However, it's important to note that Mr. Furley is actually a character from "Three's Company." In "The Fresh Prince of Bel-Air," the character often referenced for his quirky fashion is actually a fictionalized version of a neighbor, but the show primarily focuses on the Banks family and their interactions with Will Smith, rather than a specific neighbor with that attire. If you're thinking of a specific neighbor, it may have been a comedic bit involving various guest stars.
