Louis Jordan - Knock Me a Kiss (highly recommended)

Anthropologists have not reached a consensus as to whether kissing is a learned or an instinctive behavior. It may be related to grooming behavior also seen between other animals, or arising as a result of mothers premasticating food for their children. [yummy] Women are subconsciously more attracted to men whose major histocompatibility complex portion of their genome is different than her own

Kissing is a complex behaviour that requires significant muscular coordination; in fact, a total of twenty muscles working cooperatively. [I hope I don’t remember that, it might throw me off.] The most important muscle involved is the orbicularis oris muscle

Notable kisses: At the Diocleia festival at Megara in honour of Diocles, lover of Philolaus, a kissing contest was held in which boys would kiss a male judge, who awarded a laurel wreath to the boy he deemed the best kisser. . . . In Lady and the Tramp, as Lady and Tramp simultaneously eat a spaghetti noodle from opposite ends, their lips meet in the middle. [She lets go, bashful. He rolls the last meatball to her with his nose.]
