I have been looking at this all day and laughing.
Way back when my OLDER sister was about the same age as the girl above, she played a game with the family dog. Eventully it led to him jumping on her and pulling her hair. Apparently it did not really hurt and she would always end up giggling uncontrollably.
Well, the dog eventually took the game to a new level. He used to lay in wait for my unsuspecting sis. She would curl up in a blanket all cozy with her head at the edge of the sofa watching T.V. Our dog would just stare... and stare... and stare... and stare... then POUNCE! It was just like the GIF at the top. I used to laugh to tears!
Great childhood memories. Thanx tOdd.
