Feynman on his worst day is better than 80% of the rest of us on our best. This series of 3 short lectures from 1963 is fascinating and, well, a little dated. For those of us from the US who remember the Cold War & the scary Communists there is some truly interesting stuff. There's also a lot of oddness and plenty of hilarity. This is Feynman the regular guy rather than Feynman the physics prof, and well worth picking up- especially if you're a fan. If you are new to Feynman, go with Surely You're Joking, Mr. Feynman! instead.
