I have this nerdy calendar called "Jeff Kacirk's Forgotten English", and every day it provides a definition and/or anecdote. The anecdote for May 7th, 2013 is as follows:
"The shortest inaugural address on record [in the United States] was Washington's second–a scant 135 words, which lasted about two minutes. The longest inaugural speech was given by William Henry Harrison, who required nearly two hours to deliver his 10,000-word message in 1841. He offered it outdoors in strong winds without an overcoat, appears to have caught cold in doing so, and died a month later".
I am going to tell this story to my students. If you're wordy in your essays . . . you might literally DIE.
