I dated a stand up and he also lived in a nice apartment in one of Melbournes most desirable locations. He didn't have a day job either, stand-ups can make very good money, Jerry also toured a lot, there's good money in that also.

As for Frasier, he's got a high rating radio show, which is huge money and probably also has clinic hours where he charges hundreds per hour. He would be super well off.

I also recall some mentions of investments on his part.
