"Mom, how do animals kiss?"

I was stunned.  My little baby boy already thinking about kissing.  What kind of a world are we living in? As I tried to prod him for more information as to why he needed to know with no luck, I finally gave up and said, "they rub noses, I guess."

"Nope!  They lick!" he replied.

"Lick what?" I asked back appalled at the possibilities.

"Faces, silly."  

Oh.  Like puppy kisses.  Completely innocent.  Better get my mind out of the gutter.
