Tis the season for office parties, family dinners and brazen cash-grabs. Year after year, the holiday season proves that nothing is too sacred for the retail market - not even some of the very best Christmas carols ever written. Here's a sampling of some of the strangest celebrity Christmas albums that we've come across over the years.

1. Santa Trump

No, The Donald didn't release his own Christmas record. But he did guest on The Regis Philbin Christmas Album (2005), which featured the talkshow host crooning Christmas classics like "Rudolph the Red-Nosed Reindeer" - with The Donald filling in the vocals for Santa. He even "Trumpified" the lyrics by inserting "frickin'" into the song. And at the end of the tune, you can hear The Donald firing Blitzen - probably to give his spot on the sleigh team back to an American reindeer.

Check out this clip of Philbin and Trump promoting the album on The Late Show with David Letterman.

2. A Star Wars Christmas

No, this isn't the soundtrack to the dreaded Star Wars Holiday Special (1978) where Carrie Fisher serenaded a family of Wookies. This is the 1980 record Christmas in the Stars - a Star Wars concept album about a droid factory that builds Santa's toys.

The track list is full of revised carols like "R2D2, We Wish You a Merry Christmas," which was sung by a pre-fame Jon Bon Jovi (seriously). Maybe that's why he was wanted dead or alive.

3. Afroman's 40 Oz. of Christmas

Ten years ago, novelty rapper Afroman, who took stoner culture by storm with the hit single Because I Got High, released A Colt 45 Christmas - a CD stuffed with alcohol and marijuana-themed parodies of Christmas carols like "The 12 J's of Christmas," "I Wish You Would Roll a New Blunt" and "O, Chronic Tree."

4. Tinsel on Tinsel

Bob Dylan is known for odd career choices, so it's not entirely surprising that he decided to throw critics a curveball in 2009 when he released Christmas in the Heart, featuring covers of songs like "Must Be Santa" and "O Come All Ye Faithful." It's not an easy album on the ears since Dylan doesn't exactly have the voice of a choir soloist. But there's no denying that his heart was in the right place: proceeds from the album went to various charities dedicated to combating hunger.  

And the music video for "Little Drummer Boy" is pretty cool.

5. Rosie O'Donnell's Holiday Duets

Bob Dylan isn't the only celebrity who lent out his pipes to charity. In 1999, standup comic and talkshow host Rosie O'Donnell released A Rosie Christmas, her collection of holiday duets with stars like Céline Dion, NSYNC and Elmo. The Sesame Street star not only sang with Rosie but joined her on the media circuit to promote the album.

And it was just as saccharine as you'd imagine. So bad that when Rosie and Elmo invited Katie Couric to sing with them, she said "Maybe" while bolting offstage. And she didn't appear on camera for the rest of the schmaltz fest.

6. Snoop's 12 Days of Christmas

In 1996, Death Row Records - the label representing Snoop Dogg, Tupac and other gangsta rappers - released the compilation album Christmas on Death Row. The disc features hard-edged holiday rhymes from Nate Dogg, Bad Azz, Daz Dillinger and many more.

And the track "Santa Claus Goes Straight to the Ghetto," where Snoop Dogg offers a unique take on the 12 Days of Christmas.
