Boltzmann brain teaser

In his TED talk, Sean Carroll very briefly discusses Feynman's explanation about how the universe we can see and experience is not a statistically lucky perturbation, before moving on to the rest of his lecture. In other words, Feynman seems to discount the "Boltzmann brain" hypothesis, that we're not just the ephemeral product of a lucky shuffle of a metaphorical box full of marbles. Can someone explain this to me in words other than Carroll's, i.e., what evidence Feynman was using to prove his argument?
