Um, where did you say you were from, again?

This post is dedicated to my roots/origins. For all those who don't know me well enough, I'm half-Punjabi and half-Tamilian. (a stunned silence grips the audience... a few comments ripple through - "he's Tam??? No way. Wait a minute, he just can't be Punjabi either.") As has been well documented by some of my friends, I can barely speak either of my parents' native languages. The only language I can call myself competent in, is English. (shouts of "barely!" ring through the gathering)
Upon hearing my origins, people's responses have been about as varied as they come. Here are a few which I found funny:
1) "Yeah, right" - followed by laughter.
2) "What???" - accompanied with a blank expression.
3) "Impossible!" - the person went on to list a few reasons why I just cannot be tamilian. (I personally think that he was mortified at the fact that I'm half like him) Unfortunately, most of this was said in pure Madras Tamil. I stand a reasonably better chance at Latin.
4) "Eh! No way" - said with a conspiratorial smile. (just who are you trying to fool, eh?)
5) "Oh, that explains it" - and not a word more. Very discomforting.
6) "Ah, OK" - as if accepting the fact that these sort of things happen from time to time. An odd mistake here and there isn't all that bad.
7) "You're joking!" - um, yes. Don't you think I'd have come up with something a little more believable?
8) "Enna da?" - Did you not hear what I said about the language(s)???
