We were also too lazy to prepare or make powerpoint slides (which every other team did), so we just showed the website that we had made to construct the paper. The funny is is that it totally didn't matter. We knew the material inside out and we had far too much to say. All five of us spoke, and kept up the veneer of a consulting firm actually presenting to a company. Plus, going first, there was no precedent, and we could cover whatever we wanted.
The other funny thing is that George leaned over to me and said "I told HJ to bring a throng of BUH people to watch the presentation, so they could come in at any minute". heh. We quickly realized what a BAD idea that would be so we both watched the door like hawks for the next hour.
My only regret is that I didn't end with "If you have any questions, just ping me and I'll get back to you."
