Laughter is the best medicine—tell us your favorite harmless pranks from service days.
Best harmless one I used: slapped a Post-it that said “voice-activated” on the ancient coffee maker — @SgtB kept saying “brew” at it until we cracked, then we pulled it before PT so no one missed caffeine. If you try it, use painter’s tape so it doesn’t leave gunk and skip it on inspection days.
