I had Jeff his first semester at UIUC. He received a standing ovation the last day of class. He's _that_ good.
I second that, I had him in '05 and specifically waited to take the class with him as the teacher. Was well worth it, he brings a sense of humor and style to teaching that turned an otherwise difficult class into an absolute joy.

To wit, I also had Jeff for algorithms a couple years ago and he is indeed a dedicated and passionate teacher. But thank you for your support, fellow HNers!
