From a thread concering Audio/Visual Entertainment, and the various connectors and leads such equipment spawns spontaneously...
What is in your box of stuff, too useful to throw away that you now realise will never get used (but you still won't throw away...it's just too useful)
Mine contains a vast knotted collection of SCART Leads, Red/Yellow Audio Video connectors (usually with a mystery proprietary connector on the other end that is designed for a long since departed device) and RJ45 cables.
If I ever actually wanted a nasty, cheap, SCART cable then it would be quicker to drive to the shops and buy one of decent quality than to attempt to untie the knot.
Tip for manufacturers of Anchors and Grappling Hooks, make the end of your products the same shape as an RJ45 connector. They are the absolutely perfect design to snag on anything they come into proximity with.
