Proud to present the Kuch Kuch Hota Hai extended universe, one that puts the Marvel Universe to shame. Crucially, the latter does not have SRK.

So we start with the introduction of this theme tune back in 1997. SRK is into Kajol halfway through movie because she has long hair.

SRK and Kajol get back together in K3G, this time early on (she starts movie with long hair) and this time, the theme gets snuck into a fantasy song sequence next to the Pyramids. They are otherwise standing in Karol Bagh mithai ki dukaan at this point.

The theme is now iconic enough to feature in a throwaway parodic awards show sequence in Om Shanti Om.

But it's hilarious so they do it twice.

Then, in Dostana, years before Nick Jonas had learnt to walk, Priyanka Chopra's character makes a heartfelt declaration about this movie.

John Abraham is "pretending" to be homosexual at this point so that he can get her to fall in love with him, and here he reveals the next part of his grand strategy by re-enacting iconic scene.

Sadly, the legacy does not end there. Instead, Bollywood also decided to give us a sci-fi animated canine-version of the movie, because why not.
