Now seems like as good a time as any to explain why, in our family, we say "Kiss Pie!"
Back when my younger son Sam (now 20) was about 3, he came bursting in one day and said, "Splash pie in Mommy's face!" I never did know the origin of that particular exclamation -- maybe something he heard (or mis-heard) on a cartoon show or something one of his little friends said (?).
As for the origin of "Kiss Pie," after Sam's "Splash Pie" greeting, I gave Sam a kiss on the top of the head and said, "Kiss pie on Sam's head." We did that back and forth for a few weeks or months, and from that point on, the phrase became embedded in our family lingo and gradually shortened to "Kiss Pie!" as a kind of all-purpose way to say "Good night" or "Good bye" or "Love you" or "Awwwwww!"
Kiss Pie, Indeed!
