From 1983: I remember being utterly perplexed by the (presumably off-the-shelf... or out-of-a-cracker) Spinner Gun freebie cover-mounted to the first issue of MARVEL UK's new X-MEN weekly.
It only consisted of three parts (the flat plastic gun, the spinner and the elastic band) but it confounded all attempts to make it work. How could something so small and simple be so perplexing?
Clearly I wasn't alone as the British Bullpen saw fit to publish this handy guide in the seventh issue (cover-dated 15 June 1983).
By which point... I'd lost the gift. Sigh.
