Found this over at agent Janet Reid's site this morning:
How many agents does it take to screw in a light bulb?
Agent 1: Sorry, we're not accepting screw in light bulbs anymore. Bayonets only, and we only get them from the store.
Agent 2: We considered your light bulb but it's a bit too modern. Have you tried turning it into a candle?
A3: Loved your light bulb. Great light. Lots of illumination. Unfortunately, the agency's decided to remain in the dark indefinitely.
