Palin hits the Facebook the next day and rants about how much of a "kick to the gut" the episode was to say such things about her family, but her rant reveals she never saw the episode, which never explicitly mocked her son.
She was also unaware that the actress voicing the retarded girl on Family Guy is a rather famous DS actress herself! She went public with a statement:
Andrea Fay Friedman wrote:My name is Andrea Fay Friedman. I was born with Down syndrome. I played the role of Ellen on the "Extra Large Medium" episode of Family Guy that was broadcast on Valentine's day. Although they gave me red hair on the show, I am really a blonde. I also wore a red wig for my role in " Smudge" but I was a blonde in "Life Goes On". I guess former Governor Palin does not have a sense of humor. I thought the line "I am the daughter of the former governor of Alaska" was very funny. I think the word is "sarcasm".
In my family we think laughing is good. My parents raised me to have a sense of humor and to live a normal life. My mother did not carry me around under her arm like a loaf of French bread the way former Governor Palin carries her son Trig around looking for sympathy and votes.
