You would never!
Your best friend, BEANS, hand-crafted this SPY BADGE with his own mentally-unstable hands and you're going to cherish it with all your being for a time period not to exceed 24 hours from this moment.
Besides, if you were to turn your SPY BADGE into CROW FOOD, how else could you exercise your right to wield JUSTIFIABLE NOSINESS as a TRUE SPY?
Never mind that the badge says "NOT A SPY." You're pretty sure BEANS put that bit there to throw likely saboteurs off your scent. Reasonable doubt and all that.
The average citizen will take one look at this badge and assume you're someone with AUTHORITY.
