Feynman's Inbox

This is only tangentially relevant, but here's a fun audio clip of Richard Feynman actually talking about his safe cracking days at Los Alamos: http://www.youtube.com/watch?v=jJXy2QDlxT0

Also tangentially relevant is this xkcd strip: http://xkcd.com/277/

Basically, if these two links had a baby it would be the OP. :-)
