Apart from e-mails asking for advice on offing yourself, we tend to get a variety of work-related anecdotage posted to the old inbox. Today we received one such story. It's a long, detailed account of an affront to the dignity of CBS News employees. It seems unbalanced at first, but as it wends toward its inevitable conclusion, it achieves a certain kind of poetry. Should you be wary of the length, or unable to click on the jump, we'll give you the quick summary: There's some doody on the wall in the men's room, and it's been there for a long, long time. Admit it, now you can't resist.
