- Ask Frank #5 (pinecones in my urethera)

Mrs. Filthy is Filthy Frank's mother, and supposed spouse of Dade. She was once served some cereal with Frank's fart in it. She also created the recipes for rat soup, rat quesadilla, and a rat churro, but that was eventually stolen by Fake Frank. It was also revealed that Salamander Man is possibly a sexual partner that she encounters.

In the episode VOMIT CAKE Frank mentioned that his mum has terminal cancer.
