I can't picture you being mad. Your unbelievable pissed off is my mildly upset, methinks. You need to break something valuable with your fists and scare the neighbors with your swearing. If they hand deliver it, it means they care. Which is good.
I've seen him pissed, but he does it in an odd way with a smile on his face. You can't quite tell if he is going to start laughing or implode and turn into a black hole.
