Murphy Brown

From Muppet Wiki

Murphy Brown was a sitcom starring Candice Bergen as an investigative journalist and anchorwoman. The show aired from 1988 to 1998.

In the episode, "It's Not Easy Being Brown" (a reference to Kermit the Frog's signature song, "Bein' Green"), Murphy hires a new publicist that gets her a guest spot on a Sesame Street-style show. "Kelbo" (performed by Wally Wingert) and "Murphy Brown Bear" (performed by Lisa Sturz) mock the short-tempered Murphy until she tries to attack the puppets on camera, thus ruining her attempts at increasing her popularity.

Bergen did actually appear on Sesame Street in character as Murphy Brown, and interviewed Oscar the Grouch.
