Larry Hagman coming to "Desperate Housewives"

I just saw "Desperate Housewives" tonight, and on the preview for next week, we see that Lynette's mother is engaged to a character played by Larry Hagman, of "Dallas" fame. In the preview, Lynette's mother says that she is marrying him because "he's loaded".

I'm excited about this, because Larry Hagman is a great actor, and played my favorite TV character of all-time, JR Ewing on "Dallas". He could be really interesting on this show!
