RAY: Here's the answer. The reason I couldn't give you his name is that his name is John Boyd Dunlop. And Dunlop invited the pneumatic tire.
RAY: And in doing so, he made the Safety bike the bike of choice because now it was no longer uncomfortable. See, the big wheel of the Ordinary smoothed out the ride over those cobblestone streets and rutted back roads.
TOM: Of course, but if you put smaller tires, smaller wheels on the bike --
RAY: That weren't pneumatic. Bum-bum-bum-bum-bum!
TOM: Oh, man!
RAY: And all the people who rode those had their teeth knocked out so they all talked like Barry Hays.
