Rockin’ around the Christmas tree — bizarre holiday tunes.

Lucy Nieboer

Dean Martin made a fortune singing about the holidays. Barry Manilow's schlock version of "White Christmas" will hit the airwaves the day after Thanksgiving.  These numbers are a tradition this time of year but some recording artists that you would never expect also cash in on the market of merry carols.

John Travolta and Olivia Newton John's "Baby it's Cold Outside."

Looks like Danny and Sandy really did stay together after those wild summer nights. They bought a little starter in the suburbs and and now croon carols to each other in the evenings. 

Miss Piggy's "Santa Baby."

The idea that someone finds Santa sexy is disturbing. Imagining Miss Piggy seducing Santa is actually the grossest thing ever. 

SnoopDogg's "Twas the Night Before Christmas."

Spreading some of that good old Christmizzle cheerizzle. 

Fiona Apple's "Frosty the Snowman."

A folksy take on "Frosty." Cute.
