We goof around here quite often. Some days more than others.
One thing Alex and I do is grab each other on the bottom and say "butt cheeks!" I usually do it to him but sometimes the tables get turned.
Just now I was getting Alex's jacket so he could go outside to play. While I was reaching up to get it, he was grabbing my bottom and saying "butt cheeks!" over and over and I asked him to stop. To which he replied ...
"I like butt cheeks!"
He's so darn cute sometimes!
