Yeah, that would freak me out as well, particularly if it was intentional.
Also, of course a student of mine being a murderer would freak me out.
edit: It SHOULD freak you out. You should take a moment to think "Was there anything I could have done to make a difference there?" Most of the time it is probably a no, but I'd say it is much more irresponsible to not acknowledge the situation. Volo is right that it has little comparison to selling a wedding cake, but maybe he should spend less time trying to derail the thread because of a silly meme.
