Just one more...

Okay, so by this time you are perfectly fed up with me posting.  (Seven posts in one day? Geez, girl, get a life!)  And you're probably fed up with xkcd as well -- although that would be a shame because it is so darn funny.

But I saw this one, and I had to put it here.  It is geeky, geeky, geeky (although not nearly as geeky as the one about Paul Erdos -- sorry, I have't figured out diacritical marks yet) and I love it.  It reminds me of an advanced logic course I took at MIT more years ago than I care to remember (and I'm certainly not telling you).
