Fred Flintstone is a cartoon character from The Flintstones.
The Flintstones (Fred, Wilma, and Pebbles) are on the couch. When the Simpsons come in, Fred smiles at Homer and invites him to sit.
In the season six episode Sideshow Bob Roberts, Bart, who has been demoted to kindergarten by order of the mayor's office, plays with a "Flintstone phone" toy and dials up Fred, whose automated message (voiced by then-voice actor of the real Fred Flintstone, Henry Corden) is played when Bart presses a button with Fred's face on it.
