Smoker "Do"s

Spiros at Philosophers Anonymous is running a "Smoker Don'ts" thread. It has been suggested that we run a thread devoted to Smoker "do"s. I have very little experience with this thing, but my understanding of the "do"s is as follows:

1. Do go and visit every school you interviewed with.

2. Do be sober during the entire thing.

3. Do follow up on any interesting research questions that came up during your interview.

4. Do be nice, pleasant, personable, and not an asshole.

But this is just the tip of the iceberg. What else?

P.S. I am deeply sympathetic with Spiros's anonymous commenter at 1:00, who says "I cannot believe that this "smoker" business occurs! It seems totally unfair, and borderline illegal to expect people to travel to a conference for an "informal interview" that is actually mandatory."
