A man walked into the Lourve with a plastic clicking box.
He held it up to a renaissance portrait; the box didn’t click at all. He moved on to the surrealist paintings—the plastic box clicked a little. Security got anxious.
Just as they were about to stop him he moved into an exhibition on film arts and scanned the device over a full-scale model of the Xenomorph from Alien. The box exploded, clicking madly.
“Stop!” Security demanded. “What’s that in your hand?!”
“This?” he said, “it’s just my Giger counter.”
