A wobbly (but [unfallydowny]) toy from back in the day. (Actually, it originated in the [70s], which is well before MY [back in the day], but I can pretend to be cool and know what Im talking about.) (And anyway, [Playskool] still makes incarnarnations of the darn things.)
While I never had Hasbros [brand name] Weebles, I did play with a DIY version my uncle made for me. It involved a purple plastic easter egg (you know, the kind you get three jelly beans in) with a penny taped inside the bottom half and a rather frightening face drawn on in [Sharpie]. Basically, like the actual Weeble, you could bat it around and it would always right itself. It wasnt that far off from the real thing, either.
Being a somewhat [belligerent] child, I took the slogan as a personal affront, and spent many hours (well, at least twenty minutes] trying to devise ways to MAKE THE DARN THING STAY TIPPED OVER. Gluing it to the table might have worked, but I was caught before the [elmers] had set. [Would that I were] still so carefree!
Admittedly not a hugely challenging idea for a toy, but hey.
