The voice actor for Leela (Katey Sagal) played Peggy Bundy in the tv show Married… with children, which was hugely popular in the 90s. The above picture was a very common scene from the tv show. Peggy with huge hair, sitting on the couch with her husband watching tv and eating junk food. So, it’s a fun reference to her previous work.
In my headcannon Peggy left Al behind and joined up with a biker and his gang, creating a whole new life for her. Al meanwhile took the kids, left chicago for california and used his knowledge about sales to create a solid closet company. Out of that lead infested house, Kelly got her act together and met Phil - while Bud Was finally done with overcompensating.
So, it’s a fun reference to her previous work.
So then not a joke, but a reference. I understood the reference but failed to see the joke. Maybe I am just overly pedantic.
No worries! I always thought of a “joke” as something that was intended to make me laugh. When I first saw this, I laughed as I didn’t expect a reference to her old show. So I personally consider it reasonable to call it a joke. Either way, this all has made me want to go back and watch an episode or two of Married with children. Cheers!
