walrus: That was 'Flight 172'. An excellent one by Mouli. Who can ever forget the flight scene where he describes 'naadhswaram' to a north indian.
I heard it was his debut drama effort while working in Ponds. One of the greatest comedy writers in TN.
I vaguely remember another one of his 'Ammaavaasai', in which there's a hilarious scene where tries to commit suicide.

Can we recollect more such scenes?
