those rubberised caps you get with hdmi cables

we got a couple of hdmi cables recently and they came with soft plastic protective end caps. As I came from a generation who grew up watching Blue Peter, I was convinced these caps shouldn't go to waste.
Well these fit on the end of usb memory sticks, so if you're like me and tend to lose the caps to memory sticks, this will be a godsend.
However if you are like me you will lose the HDMI end caps before you get the chance to use them,
