FWIW, as someone who had multiple friends who worked closely with Andy over 5+ years and at all stages of their career (both BS / PhD) those comments reek of someone with an axe to grind. All of the many anecdotes I have about Andy paint a picture of a great advisor and mentor. I suppose I should say "shenanigans aside", but if you can't separate his jokes from his academic side you need to develop a sense of humor.
