"[William Shirer writes in his works Berlin Diary and The Rise and Fall of the Third Reich that on the morning on September 22, 1938, prior to Hitler's meeting with Neville Chamberlain over the future of Czechoslovakia] Hitler was in highly nervous state. On the morning of the twenty-second I was having breakfast on the terrace of the Hotel Dressen, where the talks were to take place, when Hitler strode past on his way down to the riverbank to inspect his yacht. He seemed to have a peculiar tic. Every few steps he cocked his right shoulder nervously, his left leg snapping up as he did so. He had ugly, black patches under his eyes. He seemed to be, as I noted in my diary that evening, on the edge of a nervous breakdown. "Teppichfresser!" muttered my German companion, an editor who secretly despised the Nazis. And he explained that Hitler had been in such a maniacal mood over the Czechs the last few days that on more than one occasion he had lost control of himself completely, hurling himself to the floor and chewing the edge of the carpet. Hence the term "carpet eater." The evening before, while talking with some of the party leaders at the Dreesen, I had heard the expression applied to the Fuehrer -- in whispers, of course."
