This will come up in news/trivia reports on presidential inaugurals, but it's still a great story:

In 1841, President William Henry Harrison gave an hour-and-forty-five minute inaugural address during a snowstorm. He caught pneumonia and died a month later.

From Bartleby.com: "President Harrison has the dual distinction among all the Presidents of giving the longest inaugural speech and of serving the shortest term of office."

Word is that President Bush's inaugural address today will be about 17 minutes.

MORE: Michael Meckler, of Red-State.com emails to say:

Harrison's speech is actually one of the best ever delivered, for it provides an important analysis over how the federal government is supposed to work, and especially on the relationship between the executive and legislative branches. And don't let the length scare you. In the 19th century, public orations were expected to last over an hour.
