Andaz Apna Apna

One of the most poular movies in Hindi Cinema has been Andaz Apna Apna. But after watching Dumb And Dumber, I realised that it might have a lot of scenes ripped off from D&D. Like the one in which after Aamir Khan adds some stuff to Salman's food, and then he has to keep visiting the restroom. D&D has the exact same scene.

But a little bit of googling tells me that D&D released on 16th Dec 1994, whereas AAA also released in 1994 (dont know the exact dates) but also that it took five years to make the film, because Aamir and salman didnt get along too well. This probably implies that D&D got the inspiration for the scene from AAA! If they indeed did, I don't know how that was possible because of the short time span between the two releases.
