While listening to Obama's speech I started to think of what would a All-time Top 5 Speech listing of all time. So with my brillance and the internet, I've came up with an error free and the one true historical reference...
#5 John F. Kennedy's Presidential Inauguration Speech (January 20, 1961)
#4 Barack Obama's Democratic National Covention Speech (both of them count as one)
#3 Abraham Lincoln's Gettysburg Address (November 19, 1863)
#2 MLK's I Have A Dream Speech (August 28, 1963)
#1 Fromdabak's 9th Grade "If I Ruled the World Speech" spoken in Ms. Willamson's English Classroom.... (Oct 1989)
