The Mansion Where The "Last Comic Standing" Live

I love that Scooby-Doo looking gothic mansion that the Last Comic Standing contestants live in. For those who haven’t seen the show, there’s this stone mansion in subrban Los Angeles that looks like a miniature European castle. Much of the stone is covered with ivy, and the exterior (and much of the interior) is filled with examples of Medeival architecture; a moat, coats of arms, etc.

Inside it’s filled with kitschy references to fantasy, horror, sci-fi and the Medeival period.

Can anyone give me some history of this mansion? Who owned it before LCS used it? Who built it?
