The guys I work with are all rather child-like (in a fun way). For example, we have a laser pointer floating around the team room. Whenever somebody finds it, they start playing with it to the point of distraction. They stare at it on the ceiling, point it at screens, each other, the floor.....
We were preparing a demo on wednesday, and one of them picked up the pointer. "We can show them our laser pointer," he suggested cheerfully, as he made it dance around his keyboard.
"Yeah sure," I said. "We'll show them that we're all catlike. And I don't mean in terms of reflexes, I mean in terms of attention span."
