And in response, thus spake the Oracle:

} Notes:
} [1] Ever since that pact with.. oh, wait, I'm not allowed to
} talk about that. Sorry. Just take my word for it.
} [2] Everyone who runs Microsoft software and has an internet
} connection, anyway. "No personally identifying information",
} hah, there's a good one.
} [3] Sorry, but yes, Santa's beard is a false one. Didn't you
} know that the most common method for disguise for men is a
} beard? Did you really think that such a long beard would be
} natural? Off with the glasses, on with the contacts and the
} huge beard, and you look completely different.
} [4] Yes, really - the Bill & Melinda Gates Foundation is in
} fact the world's largest charitable organisation, and among
} (many) other things currently funds 90% of the world's budget
} for the eradication of polio.
}
} And a final clue:
}   - Many houses these days no longer have chimneys for Santa
} to come down.
}   - Therefore, he needs an alternate method of entry.
}   - The easiest entry points to most houses are the windows.
}   - Windows is well known for being insecure, allowing easy
} access by outsiders.
}
} How much more proof do you need?
