Government of Kalimpong

This happened about 4 years ago. I think I recounted this incident so many times that I had to force myself to forget about it, lest it lost its humour. This took place between my friend RM who'd come to stay with me for a while and my father. She belongs to a little town near Darjeeling called Kalimpong which is why she has typical north eastern features. Most ignorant people mistake her for being oriental and so a foreigner. Everything but Indian. 
A little bit about my father. My father is 61 years old with a mop of thick black hair (no, he doesn't colour them). He marvels at absolutely everything in this world. His reaction to most things are "WO" (for WOW). It could be something as mundane as a train. ( I didn't say that to rhyme. In London we were sitting in the tube when another one passed us with my father exclaiming "WOH" very promptly to break the silence. So anyway,this is how it went:

Father: "So RM, where are you from?"
RM: "Kalimpong".
Father: "Ohhh. WO. Kalimpong. Achha achha. What does your mother do?"
RM: " She works for the government"
Father (very matter of factly): "Oh ho ho. Very nice. Government of Kalimpong. "
