With a nod to Texas Guinan...
Yesterday was a startling day. One of our clients came in with the idea of mounting a camera to a window - I suspect it might be for a video. When I was unable to understand exactly what he meant by a sucker he demonstrated it in mime...I shall bear that image in my memory for a long time*...a startling day...
In the event, we did have a selection of suckers. See the the large Manfrotto 241-series mounts. One is already fitted with a rigid shaft that you can grip onto and the other has a 3/8" stud to attach your ball-head to. You pump them for all you are worth and they stick like a limpet.
Ditto the smaller Cullmann variety, though here there is no pumping required - you just use a flick of the wrist to lock the lever. Not quite as much suction as the big suckers but enough to hold a small camera on.
Note that you can also get the Cullmann suckers in large accessory packs that have a number of useful table-top supports. We use them here in the editorial studio to take the blog pictures. Highly recommended.
