It has to be a joke.
But I had a girlfriend like this when I was younger so I think this joke is based in reality!
I was sick so she wanted to make me soup but she didn't know how to cook. She just threw everything in a pot, including chicken pieces, and let it all boil into a mush and then served it to me with an insane amount of fresh parsley.
Bones and all. Cartilage floating. The broth was gray from fat on top.
