A guy is walking through Chinatown in New York. He is fascinated by all the Chinese restaurants, the shops, the signs and banners on all the buildings. He is having the greatest time just walking and looking around. He turns a corner and sees a building with a sign that says "Hans Olafsen's Laundry."
"Hans Olafsen?" he thinks. "How in the world does that fit in here?"
So, he walks into the shop and sees an old Chinese gentleman sitting in the corner. The visitor asks "How in the world did this place get a name like Hans Olafsen's Laundry?"
The old man says "Is name of owner."
The visitor asks "Who is the owner?"
"I am he," answers the old man.
"You? How did you get a name like Hans Olafsen?"
The old man replies: "Many years ago, when come to this country, I standing in line at immigration office. Man in front was big Swede. Lady look at him and say "What your name?" and he say "Hans Olafsen." Next, she look at me -- "What your name?" I say "Saim Ting."
