Stewie: Hi! (Giggling and running out of the room)

Hi, I'm Wilford Brimley and I have diabetes. It hurts me to pee and it causes me to be short with my family. I can't sleep at night. The other day I stubbed my toe and took it out on the dog. And two weeks ago I ran out of vanilla ice cream and struck my wife. Then I find out my wife has been dead for six years. Who the hell did I hit?
