Guy 1: "I just killed twelve super dragons and made them into burgers." (An actual attempt at lying.)
Guy 2: "That statement is riddled with obviosty. You couldn't kill a super dragon if you tried AND there' only ten super dragons in existence."
2: A trap.
Guy 1: "Alright! The guard left his post for lunch and there's the top secret information just sitting there unlocked and unprotected."
Guy 2: "This is sooo obviosity"
