Kissing Grandparents

It's nice to know that my great grandparents still loved each other into old age.  And weren't embarrassed to show it.  Pictures like this make me even happier to be part of this family.

Uncle Larry teaches me to stick out my tongue?

Okay, so either Uncle Larry taught me to stick out my tongue at that time or it is hereditary.  I have stuck out my tongue when I'm thinking my entire life; as evidenced by this picture.  So, Larry, did you teach me this embarrassing habit or was I born with it?
