Have you ever been ill prepared for an oral presentation?

completely bombed an oral presentation? I did when I was a sophomore in college. I had to give a speech in front of the class about a public figure of my choosing. I did Mother Theresa. It was supposed to be 3-5 mins long. Mine was about 1 minute. :-( It was awful. I mean, what I said was okay...but it was just ridiculously short and the visual aid was just a poster, which was nice as far as posters go, but no one else made a poster as a visual aid, they had like video clips and such. I guess I was stuck in middle school... I got a C+ though, I think bc I Aced the first oral presentation.
