When it comes to decorating for the holidays, there's outrageous, then there's outrageous. We're talking here about the kind of extreme tinsel and over-the-top holiday lights that might make Martha Stewart cringe but make Clark Griswold envious.

And when it comes to outrageous, Lance Bass knows a thing or two. He's eager to share his yuletide enthusiasm with the world at large. "HGTV is stepping into Christmas with some of the most outrageous displays you’ve ever seen," says Lance. "We’re going to meet the most dedicated and obsessed Christmas fans around and, as a huge Christmas fan, I'm excited."

It's all there in a new HGTV special Outrageous Holiday Houses, airing Thanksgiving Day, Thursday, Nov. 28, at 11 p.m. ET/PT. As part of the special, Lance spotlights some of the most holiday-festive places in the world including Santa Claus, Indiana, and North Pole, Alaska.

“Stringing the lights and trimming the tree is a favorite tradition for many families, but there are some who take it to an entirely new level,” said Jane Latman, president, HGTV. “HGTV set out to find the most incredible, over-the-top holiday displays in Outrageous Holiday Houses and, with Lance’s help, we did.”

To get things started, the special kicks off with Drew Scott, star of HGTV’s Property Brothers: Forever Home, and his wife Linda Phan in their Los Angeles home. The couple transforms their historic home into a whimsical gingerbread house just in time to welcome family for the holidays. With edible delights galore, an ascending toy conveyor belt and handmade candy decorations adorning the exterior, Drew and Linda leave no corner untouched in their winter wonderland.

Visions of sugar plums are everywhere as Lance’s tour of the most awe-inspiring holiday houses takes him across the country and into Canada. In Dallas, Texas, a grand home is decked out to look like a Christmas Candyland, while in Bernville, Pennsylvania, a 300-acre dairy farm boasts a sprawling exhibit featuring a chicken coop/post office that receives hundreds of letters to Santa. Lance also takes viewers to a custom-built Santa train in Phoenix, Arizona, a three-story dazzling display in Alexandria, Virginia, and an elf’s playground in Toronto, Canada.
