To a septic with no sense of humour you probably are, but don't let that stop you. The world would be a solemn place if we all tiptoed around trying not to upset each other. The dude had just given up smoking if you noticed his signature, he's probably just terminally grumpy.

But please, keep your dickery to yourself and yours. This is a family show
