Melissa Joan Hart's Santa Trick!

Ah, the holiday season: chestnuts roasting on an open fire, goodwill to all men, and bribing your children into behaving themselves!

When OK! caught up with the former Sabrina the Teenage Witch star Melissa Joan Hart, she said she's found an ingenious way to turn her son's newfound love of Santa Claus to her advantage.

"Mason is almost three," she explained. "He's starting to understand about Christmas. We have the 'Good' and 'Bad' charts, so he gets good and bad checks when he's good and bad, and depending on how many he has at the end of the month, he'll get so many presents from Santa.

"So he's just starting to pick up on that, but we've gotta start with the movies like Frosty and all of that stuff."

We always knew that Santa knows when you've been bad or good, but we didn't know it was because our parents kept a chart for him!
