Why simple office pranks work better than complex ones: the psychology of perceiving familiar objects

Most prank ideas online try too hard, which usually makes them obvious immediately. The interesting thing about a fake electrical outlet prank is that it depends more on psychology than on the prank itself. People trust familiar objects automatically, especially in offices, hallways, or public spaces where nobody expects anything unusual. I remember a coworker putting a fake outlet sticker near a coffee machine area, and people kept looking confused for several minutes before realizing it was fake. After reading the breakdown on OOHUB, it became clear that realism and placement are basically the whole trick.
