Willie Norwood from The Sinbad Show?

You're likely thinking of Willie Aames, who played the character Willie Tanner on the popular 1980s sitcom "Charles in Charge".

There was no character named "Willie Norwood" on "The Sinbad Show".

It's possible you're confusing the two shows, or perhaps remembering a character from another show entirely. Could you provide any other details about the character you're thinking of?
