This one is really good ....

In some remote village of India, one masterji is teaching the Mahabharat Katha to class 6 students. He is at the 'krishnajanma' part of it.

Masterji: "Kansa heard the akashwani that his sister's 8th child is going to kill him. He was furious. He ordered to put vasudev n devaki behind the bars.

First son is born, and kansa kills him by poisoning...

Second one is born n kansa throws him off the mountain peak Third one is born..."
Now Ramu, who is smartest of the lot, puts up his hand. Masterji, I have a doubt (sounding nervous n confused)
"Ramu bete, whole india does not have doubt in mahabharata then how come u have one?"
Ramu : Masterji, if Kansa knew that Devaki's 8th child was going to Kill him, WHY THE HELL DID HE PUT VASUDEV AND DEVAKI IN THE SAME CELL ?

Masterji fainted
