I like the way Aamir act in Ads. Specially his dialogues are unique and are always a kinda hat ke (different)!
Now take his latest Coke Ad in which he is looking like a Chinka (Japanese) and here goes his dialogue –
Main madhumakkhi ke chhate ki photoo utarne raha tha…unhone meri utar di. Ab main tumhari utaroonga!
And his previous ones include – Thande Ke Saath Khana Changa, Baal Ki Dukan, Yaaran Da Tashan etc. etc.
I call it creativity and performance.
Now listening to I Love My India of Pardes and before that, I was listening to Desert Rose.
i really think that all the dialogues which aamir uses are really very different and very refreshing you want those dialoges to be heard again and again.
