OMG..my youngest son, Caleb aka: "The Caleb-Monster" used to do this ALL THE TIME!! in doorways, hallways, or wherever he could. I always thought in his mind he was probably spider man... my daughter in law, Emily, says the first time she came to our home she remembers him doing this..hahaha I just had to post this. It made me so happy!!! Great memories of my boys!!!
