I devoted every possible college presentation to coffee. It didn't matter what the assignment was. If there was a way to force it to work, I made it work. It saved a bunch of time on the research, but the assignments were all very different so they couldn't accuse me of copying my previous work. I obeyed their rules and there was nothing they could do about it.
Also when I got shaky and started talking too fast it looked like credibility instead of stage fright.
