I came up with this topic when I was watching Married with Children tonight and thought wouldn't it be great if Katey Sagal appeared on an episode of Ed O'Neill's new sitcom Modern Family. The best way she could appear is as an ex-girlfriend of Jay from years ago. What does everyone think?

The second part to my thread was asking Has one or more cast members ever guest-appeared or been a regular on a show with a former cast member.

The only example I know of is Bill Cosby and Phylicia Rashād being an onscreen husband and wife on The Cosby Show and then Cosby.
