Maxwell Edison, Majoring In Medicine

I know we've posed this point for debate before, but I feel the recent spate of macho President videos warrents a reopening of discussion.

Who is the manliest American President of all time? Is it:

...A) Andrew "You'll-Take-The-Swampland-And-Like-It" Jackson, probably our greatest native killing (or at least repressing) President?

...B) Theodore Roosevelt, the President who probably personally killed the most men?

...C) George Washington, who threw a knife into heaven?

...or D), None of the above?

If D, who? Feel free to use facial hair as justification.
