A short, finished list rather than an endless feed: 2 of the best 50th birthday quotes ever written, picked out of the full 50th birthday archive on QuoteForever. You will find J. B. Priestley and Steven Wright among them.
Read the list top to bottom, or use it as a starting point - every author name links to everything else they said, and every quote has its own page you can share or turn into an image.
