Context: John David Marks (November 10, 1909 – September 3, 1985) was an American songwriter.  Although he was Jewish, he specialized in Christmas songs and wrote many holiday standards, including "Rudolph, the Red-Nosed Reindeer" (a hit for Gene Autry and others), "Rockin' Around the Christmas Tree" (a hit for Brenda Lee), "A Holly Jolly Christmas" (recorded by the Quinto Sisters and later by Burl Ives), "Silver and Gold" (for Burl Ives), and "Run Rudolph Run" (recorded by Chuck Berry). PiYo is an 8 week exercise program that is a blend of Pilates and Yoga.  Developed by American fitness guru Chalene Johnson as part of Beachbody, PiYo is a low-impact workout that strengthens and sculpts the body, and enhances flexibility.  The Pilates part strengthens and tones the body, while the Yoga part promotes mindfulness and relaxation.  As such, PiYo provides a total mind-body workout. Milton Teagle "Richard" Simmons (born July 12, 1948) is an American fitness guru, actor, and comedian.  He promotes weight-loss programs, prominently through his "Sweatin' to the Oldies" line of aerobics videos and is known for his eccentric, flamboyant, and energetic personality. Rudolph the Red-Nosed Reindeer is a 1964 Christmas stop motion animated television special produced by Rankin/Bass Productions and currently distributed by Universal Television.  It first aired Sunday, December 6, 1964, on the NBC television network in the United States, and was sponsored by General Electric under the umbrella title of "The General Electric Fantasy Hour".  The special was based on the Johnny Marks song "Rudolph the Red-Nosed Reindeer" which was itself based on the poem of the same name written in 1939 by Marks' brother-in-law, Robert L. May.  Since 1972, the special has aired on CBS, with the network unveiling a high-definition, digitally remastered version of the program in 2005.  As with "A Charlie Brown Christmas" and "How the Grinch Stole Christmas", "Rudolph" no longer airs just once annually, but several times during the Christmas and holiday season on CBS.  Unlike other holiday specials that also air on several cable channels (including Freeform), "Rudolph" only airs on CBS.  It has been telecast every year since 1964, making it the longest running Christmas TV special in history.  2014 marked the 50th anniversary of the television special and a series of postage stamps featuring Rudolph was issued by the United States Postal Service on November 6, 2014. Rudolph the Red-Nosed Reindeer is a legendary reindeer, created by Robert Lewis May, usually depicted as a young fawn who barely has antlers, with a glowing red nose, popularly known as "Santa's ninth reindeer."  When depicted, he is the lead reindeer pulling Santa's sleigh on Christmas Eve.  The luminosity of his nose is so great that it illuminates the team's path through inclement winter weather. Rudolph's Shiny New Year is a 1976 Christmas/New Year's stop motion animated television special and a sequel to the 1964 special "Rudolph the Red-Nosed Reindeer" produced by Rankin/Bass Productions.  The special premiered on ABC on December 10, 1976.  Three years later, it was also aired on TV Asahi in Japan on December 24, 1979 under the Japanese dub title 赤鼻のトナカイ ルドルフ物語 ("Akahananotonakai Rudorufu Monogatari").

She is known for losing 70 pounds and launching a career as a fitness guru after bearing two children. "Frosty the Snowman" (or "Frosty the Snow Man") is a popular Christmas song written by Walter "Jack" Rollins and Steve Nelson, and first recorded by Gene Autry and the Cass County Boys in 1950.  It was written after the success of Autry's recording of "Rudolph the Red-Nosed Reindeer" the previous year; Rollins and Nelson shipped the new song to Autry, who recorded "Frosty" in search of another seasonal hit.  Like "Rudolph", "Frosty" was subsequently adapted to other media including a popular television special by Rankin/Bass Productions (formerly known as Videocraft International), "Frosty the Snowman".  The ancillary rights to the Frosty the Snowman character are owned by Warner Bros., but due to the prominence of the TV special, merchandising of the character is generally licensed in tandem with that special's current owners, DreamWorks Classics. Rudolph and Frosty's Christmas in July (commonly known by its on-screen title as Rudolph and Frosty: Christmas in July, or simply Rudolph and Frosty) is an American crossover Christmas television special produced by Rankin/Bass, featuring characters from the company's holiday specials including "Rudolph the Red-Nosed Reindeer" and "Frosty the Snowman".  It was filmed in Japan through "Animagic", a stop-motion animation process in the style of "Rudolph".  The film premiered in the US on November 25, 1979 on the ABC network.
