Porky Pig

Porky Pig, or Porky the Pig is a fictional character seen in various Looney Tunes animated shorts.

History
When Homer and Ned visited the tomb of Jesus, Homer called him the Unknown Savior which prompted Ned to tell him he is one of the most famous people who has ever lived. Homer then asked if he meant Porky Pig. Ned yelled to Homer that Porky Pig isn't a person, that he is a pig, and he's not even a real pig. Homer then asked Ned if Porky Pig is buried under the tomb.

When Bart was being plagued by the Black Tooth one night, which was really just Maggie in a costume, he started stuttering a lot and Lisa said that this was "no time for [his] Porky Pig impression".
