Do this:
First, distract target, then block his blind jab. Counter with cross to left cheek. Discombobulate. Dazed, he'll attempt a wild hay-maker, employ elbow block, and body shot. Block feral left, weaken right jaw, now fracture. Break cracked ribs, traumatize solar plexus. Dislocate jaw entirely. Heel kick to diaphragm. In summary, ears ringing, jaw fractured, three ribs cracked, four broken, diaphragm hemorrhaging. Physical recovery, 6 weeks, full psychological recovery, 6 months, capacity to spit at back of head, neutralized.
