Glenbogle - I agree with you that Ian is incredibly funny, but so much of his humour is in the way he delivers the lines, not just the words. Transcribed, his stuff is mildly amusing, but in person it's hilarious. Much of what I think of as Scottish humour is related to how it's done - a lift of the eyebrow, a little smile, the attitude of the body, and of course timing and tone.
