SICP taught by Abelson and Sussman [video]
I watched several MOOCs and OCW courses but this one was the first and the best I've ever came across. Most of the MOOC videos are still boring and I need to speed them up to 1.25x but SICP was so great, I could spend hours talking to my peers about every episode!
