Although many men and women consider it childish, more than 95% of them occasionally like to rub noses while kissing. Often called an "Eskimo kiss" in Western culture, this form of kissing is based loosely on a traditional Inuit greeting called a "kunik."
The film with the most kisses is Don Juan (1926) in which John Barrymore and Mary Astor share 127 kisses. The film with the longest kiss is Andy Warhol's 1963 film Kiss. The 1961 film Splendor in the Grass, with Natalie Wood and Warren Beatty, made history for containing Hollywood's first French kiss.
The first on screen kiss was shot in 1896 by the Edison Company. Titled The May Irwin-John C. Rice Kiss, the film was 30 seconds long and consisted entirely of a man and a woman kissing close up.
The first on-screen kiss between two members of the same sex was in Cecil B. DeMille's 1922 Manslaughter.
Kissing is good for teeth. The anticipation of a kiss increases the flow of saliva to the mouth, giving the teeth a plaque-dispersing bath.
