Ghanta Singh

This happened about a year ago when my family moved to our new house which we live in now.
Our older place is about 15 minutes away and my father took rounds every single day for about a month to transfer stuff from one place to another. On one such day when we reached our new place by car, my father was trying to park the car outside the gate of the colony. Simultaneously, a man behind us in his car was trying  to do the same. He rolled down his window and gestured to my father to move on up to make some more space for him but my father politely pointed to him that there was no space.The man then muttered something and rolled up his window. What followed was something that was so bizarre that I was too embarrassed to relate this account to anyone for a long time after that. I have now fully recovered from the incident.
My father got out of the car and started mumbling something while sniffing violently and incessantly. I shall elaborate on that. About 25 odd years ago, my father had to undergo a surgery for his deviated septum which wasn't quite successful. The surgery left him with a unique side effect of sniffing. My father is perpetually sniffing. It's second to breathing for him and we have become so accustomed to it that we don't realize how that might sound to people otherwise. When he gets angry and has to make an attempt to suppress it while his blood is boiling inside him, his sniffing gets louder and faster and sounds very scary to the ones who know him. It's also often punctuated with deep Santa laughs which go "Ho Ho Ho". One can tell it's the lull before the storm. Except that it's not really that calm and more like a  "It's gonna blow, oooowowowow...Volcano" moment.
Anyway so back to where we were. At this point, my father was sniffing real loud and fast. This is when my senses began to pick up the clue of  something unpleasant having happened. Except that I couldn't quite understand what and why. All I could hear between loud sniffs was this one sentence which made me think " Did I just hear that?" So, this is what happened.
Man in car rolls up his window while muttering something. My dad and I get out of the car and I begin to walk ahead. My dad behind me starts sniffing like a matador and between several Ho Ho Hos mumbles " If I am Santa Singh then you are Ghanta Singh". I pause, think "Did I just hear that?" and retrace my steps. I ask my father what happened. My father refuses to answer and begins to walk ahead. I look back at the man in car with a confused expression on my face. He rolls down his window. equally confused and to the back of my fathers head genuinely exclaims  " Sir....I just said Okay, fantastic".
Go figure.
