Nobody likes a skinny santa

One of our favorite family expressions is "Nobody likes a skinny Santa".

We've always thought this came from Rudolph the red nose reindeer, following the line "Eat Santa, Eat."

This December, Rudolph was on, and I was the only one at home. After Mrs. Claus said the preceding line, I leaned forward and she said: "The children will be so disappointed." I looked at the cats and dog in disbelief. I rewound the TV. No skinny Santa line at all. Has the line been cut? How will I ever get my children to eat fatty foods again?
