My list of 'who I'd like to meet' is looooong indeed... here are a few (not necessarily in order!)
Martin Luther King Jr. - I would love to see what he "had in mind" to do before he was killed
Eddie Veder - Pearl Jam rocks, need I say more?
Bill Clinton - You gotta love Willy!
Al Pacino - One of the best actors of the last 30 years
Stephen King - By far the most creative mind of our time
Hitler - To ask him why? And I'd take with me a few Jews, homosexuals, clean up a few homeless people, maybe a few communists, and just act like we're all "normal" people... then tell him the truth and see if I can get him to see that he was all wrong about them...
