Pengrove Pig is a character from the British version of Jolly Farm Revue, Stewie Griffin's favorite television program. In the show, he reads from his magic tome which contains every book ever written. In reality, he turns out to be a dirty disfigured old man and his "tome" contains obscene pictures of Mother Maggie. He does not appear in the American version in "Go, Stewie, Go!", although he is mentioned in "You Can't Do That On Television, Peter" and does appear on the box cover of a toy that Stewie buys in "Christmas Guy".
Pengrove is voiced by Michael McKean.
