Growing up we would always giggle at my dad because when he concentrates on something he sticks his tongue out. I always that that was kinda weird. A little different looking.

I am just like my dad... but I don't stick my tongue out. I make spit bubbles with my tongue. I have noticed it recently. When I am cleaning, when I back the trailer up on the dock, when I am concentrating.

Spit bubbles! Who knew.
