Does every couple do this?

You know Chad got me an iPad for our anniversary. Well, Jessie got Brendan one for his birthday. One of the apps that comes with it is Photo Booth. It takes pictures and you can choose different settings like stretch, squeeze, and twirl. It can be a lot of fun to play with because the pictures can look so funny. Anyway, while in Louisville this weekend, Brendan and I were showing all the hilarious pictures we had taken with Photo Booth to our family. While flipping through, I noticed one picture that Brendan and Jessie had taken that looked almost exactly like one Chad and I had taken. I wonder, does every couple do this pose when playing around with Photo Booth or is this something we can chalk up to being twins?
