Nobody's brought up the best scrutiny of the original polar bear joke idea.

Let's say he uses that joke at the beginning of his lecture and moves on as normal. Using demographic information we have at hand, namely that it's an engineering-related class setting, we can assume both that a large portion of the students have laptops and that, beyond the well-merited argument that most Asperger kids don't really have Asperger's, this IS an engineering-related class we're talking about. From this we can conclude that there is a large chance bordering on statistical certainty that a student with Asperger's Syndrom will be in attendance with a laptop.

The natural conclusion is that, provided his classroom has wireless as most major American campuses provide in lecture halls, within a few seconds of the joke being told his lecture will have been interrupted by someone providing a zoological answer to the standard weight range of polar bears after having accessed the related Wikipedia article.
