Becoming a boy?

I heard William awake during nap time so I figured it was ok to go in his room to put away his laundry. I am putting his clothes away and I hear this noise that sounds like water being poured out. I was thinking, "I didn't leave a sippy cup with him?" I turn around to find William standing in his crib. He took his pants AND diaper off. He was peeing on his bed and then through the crib bars!!!!!! He was looking at me like he wanted me to clap for him. Keep teaching him dad because he is trying to pee like a big boy but doesn't know where is appropriate.
