More Northwestern feedback from an attendee:

Dude, you rocked. Your talk was hilarious as well as insightful. It was good to finally meet ya, and thanks for signing my NR with your “Groundhog’s Day” article.
One suggestion: next time, tell more ninja stories. Peeps love anecdotes involving ninjas. (By “peeps” I mean myself and one other guy I know.)
Take care
