The below given is one of the best jokes you might have heard, but I think it is one of the best observations...

In some remote village of India, one master ji is teaching the
Mahabharat katha to a class. He is at the 'Krishna janma' ! part of it. So let him continue.

Masterji: "Bachcho, so Kansa heard the Akashwani that his sister's 8th child is going to kill him. He was furious. He ordered to put Vasudev and Devki behind the bars.

"First son is born, and Kansa kills him by poisoning; second one is born and Kansa throws him off the mountain peak; third one is born..."

Now Ramu, who is smartest of the lot puts up his handand says, "Master ji! I have a question here!"

Masterji (sounding nervous n confused): "Ramu bete, whole India does not have doubt in Mahabharata and how come you have one?"

Ramu: "Masterji, if Kansa ! knew that Devaki's child - whether 1st or 8th - was going to kill him, why the hell did he put Vasudev and Devaki in the same cell?"
