He is just hilarious! See yourself!
Here are other course materials if you are interested.
I usually don't look at the comments on Youtube, but in this case it is also worthwile. Majority of the people are praising the lecturer, some of them even express the wish to go to Stanford. An other quote from a commenter:
" I wish my teachers was like him :(
like serious 80% of the time and angry 20% of the time."
So here is my point:
The personality and the mood of the teacher matters at least as much as the wise things s/he want to tell. I am not saying that every student has to laugh through all classes, but a well placed joke or an occasional smile could help a lot.
