Rudolph the Red-Nosed Reindeer: The Movie

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 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.

 She is known for losing 70 pounds and launching a career as a fitness guru after bearing two children.
Buried penis (also known as hidden penis) is a congenital or acquired condition, in which the penis is partially or completely hidden below the surface of the skin.
 It can lead to obstruction of urinary stream, poor hygiene, soft tissue infection, phimosis, and inhibition of normal sexual function.
 Congenital causes include maldevelopment of penile shaft skin, whereas acquired conditions include morbid obesity, overlaying abdominal fat, or penile injury.
 Adults with a buried penis will either live with their condition or undergo weight-loss programs.
 However, weight-loss programs are slow and often do not "unbury" the penis; furthermore, poor hygiene from pooling of urine can lead to soft tissue infection.
 Patients will eventually need definitive reconstructive surgery and more urgent surgery if infection is present.
 Surgeons who manage this condition are either reconstructive urologic surgeons or plastic surgeons.
