The only comic strip I follow religiously is Piled Higher & Deeper (PHD), which chronicles the life of graduate students. Started by en Engineering graduate student at Stanford for the school paper, it has now a global following and is published three times a week. It is a lot about procrastination, delaying graduation, job markets angsts, frustration with undergraduates/research/advisers/money, finding free food and spending holidays in the basement labs. Many can relate to all that.
