Grandpa's Trick

Look familiar anyone? I'm sorry for any of you who read this that are not my sibling or parent, it's kind of a family thing.

So we were sitting at the dinner table the other night and I look over at Erin and she starts doing this (see video). I know that Shelby already knew this little trick but I don't ever remember showing Erin so it kind of surprised me. I laughed pretty hard and figured grandpa must have taught her his trick last time she was at his house. Thanks for the laugh grandpa!
