Vivek comedy actor-which movie?

This movie scene was aired in one of the Vivek's comedy scene in Tamil channel.

A bus stops at a place(maybe Ooty) and Vivek gets down. There, a young boy and young girl also get down with their suitcases and they stare at each other. Vivek comes and comments on them.

This movie released before 2008 or 2006.
