This may look like a standard Canon 24-105mm lens, but it's really a coffee mug. A very awesome coffee mug.

It's got all the details you expect to see on a lens like this, including a lens cap for a lid, rubber grip focus and zoom rings. It even has an auto-focus switch that really thwacks back and forth. Just don't try to take any pictures with it, or you'll ruin both your camera and a perfectly good cup of coffee.
