Santa Claus and his origin are mentioned in Tim Allen's show Home Improvement.

When the Calvin family is attempting to fly the cart into a vortex, Cal, the only one who can see the vortexes, has his eyes closed due to his fear. The horse tells him to open his eyes and he responds. Cal is not supposed to be able to understand the animals' speech. That's Sandra's magical ability.
