I will still guarantee you he doesn't REALLY know who Capone is or what he did. I mean, he didn't know what Pearl Harbor was for Pete's sake. Come to think of it, he probably HAS heard of Capone because he saw a movie in the 80s ("The Untouchables") where DiNiro played an excellent Capone, but I still bet his limits of knowledge on the subject are that Capone lived in Chicago, went to Alcatraz (I doubt he knows why), and beat a guy to death with a baseball bat (which there's no evidence it ever happened).
He reminds me of an SNL skit where - I think it was Charlton Heston - would go around reading Dr Seuss books as his new economic plan and there was a puppet master behind the whole thing. No, there's no puppet master here, I'm just saying he comes across as just riffing nonsense at the drop of a hat.
