The Tasmanian Devil, often referred to as Taz, is an animated cartoon character featured in the Warner Bros. Looney Tunes and Merrie Melodies series of cartoons.
In "Farmer Guy", Peter says that the tornado could be a Tasmanian devil, referring to Taz.
When Peter promises Lois to be gentile in his attempt to help Jesus lose his virginity in "The 2000-Year-Old Virgin", he claims he will be as gentile was the Tasmanian Devil tucking in his kids. A cutaway shows Taz reading a bedtime story. After he finishes, he kisses his child goodnight and starts to wind up his routine tornado exit, only to pause and gently slip from the room.
While working with Taz in "The Jersey Bore", Peter finds out he's not as wild in person as he appears in cartoons. In this appearance, he's voiced by Mike Henry.
