Try self time out...Put him in a safe place and lock yourself in washroom (time out for 1 minutes).
Don't forget to give him a DIRTY look like:" you are in DEEP trouble!" before you close the door at him.
Imagine how he is 惶惶然 out there wondering what will happen to him is a great amusement for you to calm down.
It works for me. You might want to try.
