“Langdon turned to Sophie. "Who is that? What... happened?"Teabing hobbled over. "You were rescued by a knight brandishing an Excalibur made by Acme Orthopedic.”

“...despite the headmaster's romantic claims that the origin of the cravat went back to the silk fascalia worn by Roman orators to warm their vocal cords, Langdon knew that, etymologically, "cravat" actually derived from a ruthless band of Croat mercenaries who donned knotted neckerchiefs before they stormed into battle. To this day, this ancient battle garb was donned by modern office warriors hoping to intimidate their enemies in daily boardroom battles.”

“Coincidence was a concept he did not entirely trust. As someone who had spent his life exploring the hidden interconnectivity of disparate emblems and ideologies, Langdon viewed the world as a web of profoundly intertwined histories and events.
