I once walked into a roving band of Muay Thai experts, giving it large they were. I was calm and collected, told them to stop pretending to kick the trees - they were enraged, came at me from all angles, flying kicks, shin kicks, punches - going all out at me. Luckily, I used my Cambodian Mountain Goat Herding Special Forces training to systematically destroy them, using only my keys. Depending on the size of the oncoming Muay Thai master I would change the size of the key. I unlocked them all.
