Zac Efron appeared on The Today Show this morning to promote his new film and this weekend's SNL appearance. Little did he know that Kathie Lee — whose singing son, Cody, Zac played on SNL — was waiting in the wings to ambush the poor actor. In rollers and holding a headshot of her dear baby boy, Kathy said she wouldn't let her son “leave the house” with Zac's signature coif, yet urged the star to call her son: “no really, he wants you to call him.” Is this actually an SNL sketch?
