Look what Gaga taught Karsten

Karsten's great-grandma 'Gaga' is in town for a visit. One of her favorite ways to get Karsten's attention is to wiggle her tongue back and forth and make noise. When we were getting Karsten ready for bed tonight, he stuck his tongue out. It took us a minute to figure out what he was doing, but then we could see that he was trying to move his tongue - it was hilarious!
