Google says Oprah's net worth is $3G, and Shaq's is $350M. If neither is "wealthy", then I guess the word is reserved for Bill Gates (but not that "white man signing Shaq's check", in all likelihood.)

If he weren't a comedian, I'd say Chris Rock is so full of shit it's not even funny, but I guess they're two separate things (meaning that in this instance he's objectively full of shit, but that has nothing to do with him being subjectively not funny to me; there are other comedians who're just as full of shit, but I still find them funny.)
