Television movies during the holiday season are a particular delight. Mostly because — from the random storylines to the even-more-random casting — they’re completely crazy. Tonight’s entry from ABC Family, an original two-hour movie titled The Mistle-Tones airing at 8 p.m., is no different. Thus, here are the five reasons you should tune in:

1. Cat fighting between Tori Spelling and Tia Mowry! Well, there’s no real fighting — physically, anyway. But the Beverly Hills, 90210 and Sister, Sister alums trade a lot of spicy words, as the pair battles to rule the holiday group-singing circuit. Which brings me to…

2. The soundtrack! It’s already available on iTunes. If you like Glee and the holidays, then you’ll love this. Spelling’s group The Snow-Belles sing Mariah Carey’s holiday standard “All I Want for Christmas,” while Mowry’s Mistle-Tones group sings “Please Come Home for Christmas.” They all come together in holiday unity to sing “The Twelve Days of Christmas,” too. It’s really special.

3. Tori’s wardrobe! She wears a loony fur hat at one point and, thankfully, she turned in a winky performance suggesting she realizes just how silly her role and the whole movie is.

4. Carl Winslow pops up! That’s right — the ever-classic Reginald VelJohnson plays Tia’s dad. From TGIF’s Family Matters to… ABC Family’s The Mistle-Tones. Yep. It doesn’t get any better than that. And truly, with that casting, it’s clear that ABC Family very squarely knows its viewing audience.

5. The sing-off competition! Simply put, it’s just amazing. That’s when Tori’s group sings “All I Want for Christmas,” and there are other entries from acts like Ludacris Kringle (yes, really!) and The Chest Notes, a group of what seem to be singing Chippendales dancers. Nothing will kick off your holiday season quite like four half-naked men singing “Deck the Halls,” trust me.
