I don't know whether it was mere coincidence or what!
Recently while surfing I came on DD. I stopped there for some moments as one serial was being telecasted. Cast included Varun Badola and Shweta Kawatra (Pallavi of Kahani Ghar Ghar ki). I found same dialogue-same situation, same story that I watched one or two days back.
So, the serial which was not clicked on DD that aired in 2006- three years back, became super hit on Sab Tv. So hit that now it has been telecasted twice in week!
