Well...to even discuss such matters openly is in direct violation of a paladin's code. You also shouldn't be:
Shaking hands after coughing, Mr. Immune-to-disease!
Or sneezing wihtout a hanky!
Or spitting your tobacco juice in a cup and leaving it on the table at someone's house party!
Or smoking in public, for that matter!
You better straighten up sonny-boy, or you're going to find your self busted down to "warrior" in a Sandpoint-minute!
