Ezra vs cookie dough

I cut Ezra's hair last week and he squirmed all over the place. One day I will hopefully be formally trained, but for now I do the best I can. As he was licking every last drop of cookie dough out of the bowl I saw a line across his head. I thought to myself what an awful job I did not blending the top of his hair until I realized...he'd been sticking his head in the bowl trying to clean it out with his tongue.
