If you haven't watched the speech yet he does do a great Clinton impersonation!
I also loved how he integrated the Clash! Pop culture is a great learning tool, needs to be used more often!
Starting about 23:47, Bono talks about The Clash, U2 and social activism. He ends this part by saying -"I'd just like to point out that none of your professors, not a single one, not ever, has ever drawn or is likely to draw the connection between the Arab Spring and The Clash."
This one shows his brilliant humor. All the inside jokes about the East Coast colleges was very funny too. How does he know this stuff?
I put the Clash one on my Facebook yesterday along w/ this and a link to the video - "We must not let this economic recession become a moral recession."
