Carol Burnett guest-starred on the hit sitcom "Mad About You" several times as the mom of Jamie (Helen Hunt). “They were both consummate comedic actors,” Burnett says of Hunt and costar Paul Reiser.

“I really love it when a show is funny because it’s character-driven as opposed to setup, setup, joke, laugh track. And that was all character-driven.”

I remember those episodes. Always nice to see a new thread started by someone other than myself.
