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.
