Our very own Stacy wrote a really neat article titled 12 Things You Might Not Know About A Christmas Story (even though you've seen it 90 times). Here's a couple of examples:

7. Next time you’re in Cleveland, you can visit the original
house from the movie for only $7.50. It was sold on eBay in 2004 for $150,000. Collector Brian Jones bought the house and restored it to its movie glory and stocked it up with some of the original props from the film, including Randy’s snowsuit.

8. Director Bob Clark got the idea for the movie when he was driving in the car with a date. He heard Jean Shepherd on the radio doing a reading of his short story collection, “In God We Trust… All Others Pay Cash,” which included some bits that eventually ended up in A Christmas Story. Clark said he drove around the block for an hour until the program ended, which his date was not too happy about.

My favorite bit from the movie is when the family ended up at a Chinese restaurant (fra ra ra ra ra) on Christmas day because that's where we always end up as well!
