It's a safe bet that you, and anyone you share a room with, won't get much sleep for, oh, the first week that you own this Super Mario Bros.-inspired light. You see, much like the Question Blocks in the video game, this lamp makes a "Ping!" sound effect whenever you press it.
Alas, it doesn't spit out any gold coins (or mushrooms, or bean stalks, or ....). Not that you'll need any, mind you, as it's reasonably priced.
Licensed by Nintendo, the 7-inch-square Question Block Light is perfect for the nightstand, the desk or that cabinet where you stash your classic NES. It's available for $36 from Firebox.
