Celebrate National Pledge of Allegiance Day by witnessing its epic use in one of the greatest movies in cinema history!

On this day in 1945, Congress officially recognized the Pledge of Allegiance in its original form. Congress would later add 'under God' during the Cold War.

The Pledge has appeared in a number of movies through the years, but never so effectively as in National Lampoon's Christmas Vacation. Well, in my opinion anyway.
