I'm going to start off by apologizing - there is just NO way this is as funny typed out as it was last night.
Fred and Elliot got home from swimming and I had the task of changing him out of wet clothes and I got as far as stripping him naked before he took off running. (It's a new fun game to run away from me.)
He stopped in the hallway to listen for where da-da might be and oooop! out came pee. He was peeing on the floor. He looked down at where this was coming from and gave me the most priceless look of shock, wonder and amazement and proceeded to pee again.
At this point I am laughing so hard that I not only cannot stop but tears are rolling down my face. He pees again - I can't move. I am stuck on the ground laughing and crying and barely catching enough breath to laugh again.
Fred comes out of the bathroom and scolds me for laughing (positively reinforcing, as he put it) at this behavior. It took me about 3 minutes to get out that I'm not laughing at what he's doing, it was the look on his face. It wasn't long before Fred was laughing too - but I would bet money it was the contagiousness of my laugh and still not the pee on the carpet.
I still giggle when I think about it.
