Moses, Jesus, Buddha, Mohammed, Caesar, Ben Franklin, George Washington, Hitler, Stalin, Mao, Genghis Kahn, Kublai Kahn, whoever first invented writing, whoever first harnessed fire, whoever first crafted a purpose built weapon, whoever invented farming, whoever invented the water wheel, whoever invented fireworks. In no particular order, and for different reasons (Hitler gonna get punched, for example but all of them would be interrogated, and most of them politely). And I surely left hundreds off the list who deserve a look too.
Edit: Oh and Socrates, because I want to see if he really tripped people who walked by sometimes or if that’s just a metaphor for his crafty mind.
