Video of William Not Rolling Over

So this morning, while I was asleep and Adam was tending to the baby, William rolled over! I know, I know, my baby is a genius. But how unfair is that? I spend all day with him, every day, and I make sure he has "tummy time" every day, and he rolls over for the first time for Adam? Pshaw. Later we spend like fifteen minutes trying to get him to roll over for the camera without success. Above is the footage of the attempt.
