If I bought this, I would have to revise all my jokes about "how many (category) does it take to screw in a light bulb?" Some of them won't even make sense any more, viz., "How many flies does it take to plug in a light bulb?" What a stupid product.
The primary purpose of the GU24, as I understand it, is to preclude the use of incandescent bulbs in the fixture. This may not make much difference for your typical chandelier, but for a "mushroom" type light, this allows the manufacturer to skip a lot of the heat shielding they'd normally need to include, and to produce a slimmer-profile design.
I have a large number of GU24-socketed fixtures in my house. Though I've never had to replace a bulb (these also fit LED bulbs, and I use a mixture of both), I have a 4-pack of CFLs that I bought at Home Depot sitting in my closet. I believe they were about $2.50 apiece. They're just on the shelf; no need to special order or anything.
Oh, and lastly: your joke still makes sense, as it's not a simple plug. The GU24 is a "twist-and-lock" mechanism; the male end of the bulb mates into the female end of the socket without any metal-on-metal contact, and then you twist it into place. See http://tinyurl.com/cxoy5hx .
