"A kiss is a lovely trick designed by nature to stop speech when words become superfluous."
(Ingrid Bergman)

A kiss is something you cannot
give without taking and cannot
take without giving.
(Anonymous)

Kiss till the cow comes home.
(Francis Beaumont)

What of soul was left, I wonder, when the kissing had to stop?
(Robert Browning)

We turned on one another deep, drowned gazes, and exchanged a kiss that reduced my bones to rubber and my brain to gruel.
(Peter De Vries)

a peach is a peach
a plum is a plum
a kiss ain't a kiss without some tongue
... so open up your mouth
and close your eyes
and give your tongue some exercise...
(Diesel)
