DRS is a bit like the movie Inception.
Decisions within decisions.
Technologies within technologies.
You never can be sure of whether the batsman was ever really out or not.

DRS = Decision Review by Schrodinger.
Every decision is out and not out at the same time.

Every decision given by the DRS has a parallel and opposite decision in a parallel universe.

Australia was playing such good Test cricket after ages that the Rain God couldn’t believe it and came to watch.

Phir us pe paani pad gaya.
