What was the coolest assignment you ever got in school/class?

I had a communications class in college where they tought you how to convince different groups of people of the same thing using different methods in a speach. I was majoring in U.S Government and Politics so when the final came around the assignment was to do 2 speeches as if you were selling something to 2 different crowds in front of about 1,000 people, my professor gave me Democrats and Republicans, and I had to sell them the idea of giving Alaska to Canada for funsies.
