what are the three and four people you would like to meet in any time period without screwing up history

I would like to meet Sam Bufford, Joshua Chamberlain, and Sun Tzu for the three people.

For the four people, it would be the same except I would add Henry David Thoureau.

Not to be off topic, but HOLY CRAP!! Brandon came on!!!

Now for my 4 people... Hmm...
1) Abe to see if he was honest cuz I don't believe the Geico commercials
2) George Carlin cuz he's hilarious and cuz he narrated my fav kid show, Thomas the Tank Engine
3) Hitler to hear him speak like at his huge Nazi Germany speeches
4) The creator of Nintendo so I can thank him for giving me something to do all day

Nikola Tesla, Mark Twain, ...
...That's pretty much it.

if we meet all the people at the same time I would want to meet myself from one, two, three, and four days ago... then I could beat myself at Team Fortress Two... and we could have Portal Races...

but i want to cuz I doubt you know who some of the people are I choose.

For instance, Sun Tzu is the supposed perfect strategest for war, he had lived supposedly around 500 B.C., wrote The Art Of War, and somewhow predicted how a lot of major battles in war would turn out. That is why I would like to meet him, I just want to see if is true.

Sam Bufford to me, I have to agree with Sam Elliot. He really is the unsung hero of Gettyberg. He had supposedly held the high ground for the union with I believe less than two thousand troops against more than four thousand confederates. Also, according to the movie Gettysberg, he supposedly predicted the batte of Gettysberg.

Joshua Chamberlain because what he did at Gettysberg was amazing if I heard right and I'm sure you know what he did.

Henry David Thoureau simply because he is an interesting fellow and I agree with a lot of what he says.

Henry David Thoreau was a insane to some extent in my opinion. How he stayed at Walden pond and tried to live away from society like those Transcendentalists do...
