J.D.: So, I've been asking around, and apparently you're known as one of three people: Nigel, the Brit; Klaus, the dim-witted German - yes, I said "dim-witted; or a simple, good-natured stutterer named Efram. Am I the only one that knows the real you?
Janitor: Who says this is the real me? [Nigel] Perhaps this is? [Klaus] Or this.
Doug: Hey, Klaus. In your country, how come Hamburg and Frankfurt, they have nothing to do with hamburgers or hot dogs?
Janitor: [German accent] Why is your Lake Titicaca not filled with boobs and poop?
