I remember my dad telling us about the time he was in town few weeks before Christmas back in the early 80’s when rubik’s cubes were all the rage,and some street seller had them on display on his table,my dad being inquisitive lifted one while the fella was shouting rubik cubes for sale genuine rubik’s going cheap,my dad said these aren’t real they don’t have the official rubik mark or something like that,the fella turned around told him to fuck off,hahahaha..
