4. Jerry Seinfeld
Estimated Net Worth: $800 million
His TV show about nothing has earned $2.7 billion in 12 years and could take in $200 million more a year, thanks to syndication payments. Seinfeld has spent some of his portion buying up New York real estate and has a four-car garage (in Manhattan!) for his fleet of vintage motors. The cash-rich star may need another hit: The Marriage Ref wasn't it.
