Carly wishes she had a "normal" brother after Spencer's magnetic tree sculpture catches fire incinerating all of her presents. Magically a Christmas angel named Mitch appears and sets out to earn his wings (Chicken Wings, that is) by showing her what her life would be like if Spencer were a buttoned-up lawyer: Sam's in a Juvenile Detention Center since "normal" Spencer never allowed the girls to play together. Freddie's smitten with an obnoxious girl at school. Spencer is engaged to Mrs. Benson, and Nevel Papperman is Carly's boyfriend! Only if Carly earns her lesson, will her Christmas and her life be happy once again.
