Watch: Tiffani Thiessen and Mark-Paul Gosselaar reunite for a little Christmas cooking
Zack Morris, please report to Mr. Belding's office for your cheeky sense of humor.
Pitch star Mark-Paul Gosselaar heated up the kitchen of his Bayside bae, Tiffani Thiessen, for her special Christmas at Tiffani's airing Sunday.
In the exclusive clip, the woman who played our childhood style icon, Kelly Kapowski, called her TV husband "babe" causing visions of a Saved by the Bell montage set to How Am I Supposed to Live Without You to run through our heads. Thiessen's husband, Brady Smith, and Gosselaar's wife, Catriona McGinn, don't mind right?

Not only was Gosselaar helpful in the kitchen, he handed Mrs. Morris a joke when he asked for feedback on his tossing of her fennel and sun-dried tomato dressing.
Tim and Elisa DeKay and Jason and Naomi Priestley also join in for the nostalgic fun.
Christmas at Tiffani's airs Sunday at 8 p.m. ET/5 p.m. PT on the Cooking Channel.
