If Karan Johar made Interstellar, first of all, there will be a love triangle between TARS, Dr. Brand and Cooper and before getting seprated from the two, Cooper will give some courtship tips to TARS, Kyunki Kya Pata Kal Ho Na Ho.
Professor Brand , (who will be a gayish character) will have a secret crush on Dr. Mann. While his daughter is leaving, he will say that dialogue which has now become cliche over the years , yeah.. You guessed it right, Ja Beti Ja jeele apni zindagi and that poem ‘Do not go gentle into that good night’, will run in Background (Sung by Sonu Nigam).
Ofcourse Cooper will not be able to complete the mission because Murph will have a common cold (established by one sneeze) and the next thing we see is Cooper is in a space shuttle crossing all the barriers of OuterSpace, Quantum mechanics and Relativity to find out that Murph has already reached to a Space station which is called Dharma Productions and it is currently orbiting Saturn.
But how did Murph reach to this space station…. Well for that we have to go in flashback (It’s a Karan Johar film). Just to take audience in Suspension of Disbelief, Cooper was sent to Space (aur ek love song bhi shoot ho gaya OuterSpace main). The actual plan of NASA was to organise a ‘Astronaut Of The Year’ competition which has three rounds- Space Shuttle race, Humanoid -Human dance ball and Treasure hunt. Murph wins the competition and gets Rohit Mehra’s (Not Rahul) old computer as a prize. She clicks four random keys on the keyboard , which sounds like my father’s burp *Om, Om, Om, Om* and in the next scene she is in a space ship with Jadoo and they go to a space station near Saturn. (Fuck Fifth Dimension, Black Hole, Wormhole, who needs all that when we have Jadoo). Kajol is already waiting there for his guest appearance (It’s a Karan Johar film).
Once, Cooper reaches to the train station, Murph throws a party in which she invites all the famous celebrities from different galaxies.
