This speech from Will Ferrell to Harvard Grads in 2003 is hilarious:
This is not the Worcester, Mass Boat Show, is it? I am sorry. I have made a terrible mistake. Ever since I left "Saturday Night Live," I mostly do public speaking now. And I must have made an error in the little Palm Pilot. Boy. Don’t worry. I got it on me. I got the speech on me. Let’s see. Ah, yes. Here we go.
You know, when Bill Gates first called me to speak to you today, I was honored. But when he wanted me to be one of the Roxbury guys, I — Sorry, that’s Microsoft. I’m sorry about that. Star Trek Convention. No. NRA. NAACP. Dow Chemical. No. But that is a good one. That is a good speech. The University of Michigan Law. Johns Hopkins Medical School. I’m sorry. Are you sure this is not the boat show? No, I have it. I do have it on me. I do. It’s here. Thank you.
Ladies and Gentlemen, Distinguished Faculty, Administrators, Friends and Family and, of course, the graduating Class of 2003, I wish to say hello and thank you for bestowing this honor upon me as your Class Day speaker. After months of secret negotiations, several hundred secret ballots, and a weekend retreat with Vice President Dick Cheney in his secret mountain bunker, a Class Day speaker was chosen, and it was me. You obviously have made a grave error. But it’s too late now. So let’s just go with it.
