I don't know how I get so lucky. I just found a site that includes this gem in the archives (under May 20, 9 PM, slightly edited for content because my family reads this):

Boss: Where is Luke*?
Assistant: He took a day off. His brother got meningitis.
Boss: ... If his brother doesn't die he will be a complete idiot for the rest of his life.
Assistant: How you know that?
Boss: I had it as a child.
