I'm fairly sure...
- this is not the exact object I've got the idea from;
- the original explanation I've read elsewhere (where???), is not 100 % the same as this;
- I don't know where the hell the Magnum-parallel came from;
- I still can use the "caricature"-part of the explanation;
- it still makes sense on a very "modern" level;
- the original explanation didn't mention pin-ups;
- this needs more research;
- it's too much work for a so pointless-little SGA fic.
