Shaftoe didn’t believe a word of it at first. He pegged it as some kind of British humor thing, some kind of practical joke/hazing ritual. In general he doesn’t know what to make of the Brits because they appear (in his personal observation) to be the only other people on the face of the earth, besides Americans, who possess a sense of humor. He has heard rumors that some Eastern Europeans can do it, but he hasn’t met any of them, and they don’t have much to yuk it up about at the moment. In any case, he can never quite make out when these Brits are joking.
