[Alfred is washing dishes while Dick is sitting on the kitchen counter]

Dick Grayson:
Alfred, do you know anything about Bruce's training in Japan?

Alfred Pennyworth:
Of course, dear boy, I was there. Lovely country. I especially like the tea.

Dick Grayson:
You ever hear of somebody named Kyodai Ken?

Alfred Pennyworth:
Oh, indeed. He was the only student at the martial arts school who could consistently defeat Master Bruce. A bad egg, that one.
