Chachi

So, Ankit watches this song "Bardasht" from the movie "Humraaz" many times. The actress, Amisha Patel, is Chacha's (Chacha = Dad's brother) favorite.

Ankit asks Chacha: Who is that girl?
Chacha says: Its your Chachi (Chachi = Chacha's wife)
Ankit: Ok..

After this, everytime Ankit sees Amisha Patel dancing in that song, Chacha reminds him that it is Ankit's Chachi on the screen.

Finally, after many such "See, there is your Chachi dancing again" dialogues, Ankit asks Chacha: "If she is my Chachi then how come you are not dancing with her and that other guy is".

Chacha is looking for a new Chachi.
