In a highly meta exchange, Kat asks Jenna Von Oÿ, "What ever happened to the one in the flower hats?" to which Jenna responds "I heard she's hosting quiz shows." The one with the flower hats is obviously Mayim Bialik herself, and the quiz show refers to her stint hosting Jeopardy! (1984).
Jenna Von It was the voice of one of the animals on Dr, Doolittle 3 (2006). Kyla Pratt was the star of that movie.
