<p>In dark-humour, Long-nose comes from Pinnocchio, and represents a compulsive and habitual liar in the spirit of Disney's condescending humour.<br>
As for the Nikkors, there is the AI 50mm f/1.8 as well as the Ai-S 50mm f/1.8 which have the same optics and focus down to 0.45m and is slightly longer, wheres there is the Nikkor Ai-S 50mm f/1.8s which is somewhat of a pancake lens focusing down to 0.6m and looks more like a Nikon series E 50mm f/1.8 and are never referred to as short-noses, but just pancakes.</p>
