"___ the Vegetarian" (1995 episode of "The Simpsons") (4)
I believe the answer is:
lisa
(Other definitions for lisa that I've seen before include "Leonardo da Vinci painted the 'Mona ....'" , "Mona . . . ., famous painting by Leonardo da Vinci" , "Mona ..., also called La Gioconda" , "Girl" , "Most intelligent of Marge Simpson's children" .)
