Shihan dosn't really have too many 1 liners, the only thing that came to mind was that he qiute often asks the class "What do we call those people" usually refering to outragiously flexible people, to which he gets the reply "Freaks, shihan". OT slightly, Back in High School, I had a teacher that would always walk into the class 10 minutes late and say "Alright Folks, Fiddlies down". Never worked out what a fiddly was.
