I don't know if I should bring up the connected molecules of Racemic acid, and Tartaric acid.....the former being dextrorotatory,(polarizing light in a clockwise direction) and the latter, being levorotatory (anti-clockwise)....Even molecules have this ID crisis!
Or should I mention that 668 is the "Neighbour of the Beast"
Or....should I just get me coat........Ralphie !
