Det perfekte kysset

There have been five great kisses since 1642 B.C., when Saul and Delilah Korn’s inadvertent discovery swept across Western civilization. (Before then couples hooked thumbs.) And the precise rating of kisses is a terribly difficult thing, often leading to great controversy, because although everyone agrees with the formula of affection times purity times intensity times duration, no one has ever been completely satisfied with how much weight each element should receive. But on any system, there are five that everyone agrees deserve full marks.

Well, this one left them all behind.
