The best pranks are the subtle ones, like this cool new Man Trapped Behind a Wall Grate Graphic. Simply stick this creepy, photo-realistic wall graphic depicting a man trapped behind a heating duct on the wall somewhere that doesn't seem out place and wait to see who notices it first. It's backed by 1/8" thick plastic that lifts the art piece off the wall, giving it a realistic 3D effect. This fun illusion is sure to elicit everything from mere chuckling double-takes to full blown panicked screams from your victims.
