I've loved PhDComics ever since I came to the US in 2000. It rings so true if you've ever been in graduate school (not b-school though:))
Based on the way the storylines of the two principal characters are proceeding though, I can't help wondering if Jorge is bringing the strip to a close? Here's a good link to get you started on the strip.
Update: Jorge just blogged that that's not the case. If Mike and Cecilia graduate though, the world will not quite be the same.
