I'm sure everyone gets them, the interesting question is whether they're
evading your spambayes filter.  They don't seem to give mine particular
trouble (of course I train on those that score Unsure; I'm not sure I've
ever seen one score as Ham).

There's no official corpus, else we'd be teaching the system to recognize
that corpus.  Alex gave the right pointers to docs for the testing
framework.
