The Rapper: Uncle Luke
How He Got Involved With The Adult Film Industry: He started a series of flicks called Luke's Freakshow during the late 1990s.
The Result: You didn't think we'd do a list like this and not include Luke, did you? For two or three years, he produced and hosted a handful of XXX movies. And, we're not sure why he ever stopped. Given his track record, it seemed like a pretty solid second career.
