Lois Griffin is Peter's wife on Family Guy and is voiced by Alex Borstein.
Lois was born to the wealthy Pewterschmidt family in Newport, Rhode Island. Lois ended up marrying Peter, who was from a lower-income family, when she met him as a towel boy in her country club. Yeah, none of us can figure out why she married him either.
Lois is a wonderful mother to Chris, Meg and Stewie, although Stewie is constantly trying to kill her and all.
Stewie: (Comes into the bedroom) Lois! Lois! Lois! Lois! Lois! Lois! Mom! Mom! Mom! Mommy! Mommy! Mommy! Mama! Mama! Mama! Ma! Ma! Ma! Ma! Mum! Mum! Mum! Mum! Mummy! Mummy! Mumma! Mumma! Mumma!
Stewie: Hi! (Giggling and running out of the room)
Stewie: (looking in the barrel of a shotgun) Go ahead, mother! Do it! Shoot me! Shoot your little baby Stewie!
Lois: (dramatic pause; her arm holding the gun shakes then she drops on her knees, dropping the gun) I can't do it! You're a terrible, evil child, but you're still my baby, and I could never hurt you.
Stewie: Well, that works out perfectly because I CAN HURT YOU! (grabs the gun and aims at Lois' face) Say hi to Cleveland for me! Oh, and Mr. Weed.
(dramatic pause; a gunshot is heard, Lois is unhurt, Stewie looks down at his bleeding chest, another shot is heard and hits Stewie in the head; Peter is seen holding a smoking gun)
Peter: It's just been revoked!
Brian: Uh, Peter, we didn't really set you up for that Lethal Weapon line. It... it doesn't really work here.
Peter: Oh... I'll have what she's having!
Brian: That's... better?
