Pig

Pig is a character in the comic strip, Pearls Before Swine by Stephan Pastis

Personality
Pig is a good-natured pig. He believes that there is good in every being, even his cynical housemate Rat. As well as being friends with Rat (despite Rat's constant abuse), he also frequently is seen talking with Zebra and Goat.

Pig is very dimwitted and naïve, often being beaten up by Rat after trying to have a serious conversation with him, only to say something unrelated (i.e. Euthanasia being confused for "Youth in Asia"). Pig is usually oblivious to how cruel Rat is.

Pig, when on a date, is most likely seen with Pigita, but earlier in the strip, he can be seen with other pigs. Pigita, like many people, is aggravated by Pig's stupidity. She also has dramatic mood swings.

Not much is known about Pig's family, although Pig writes letters to his mother occasionally, and she writes back with indifference to him. He also has a sister who had a brief relationship with Rat, Farina.

History
Not originally in the strip, Pig came from a past attempt to get syndicated by Pastis, and stepped into Pearls to replace the humanoid Poe from Pastis' first strip to feature Rat (also rejected).
