Who's the God of Sanity? (I've got some unanswered prayers)

Me: I've just got a text message on my phone. Who is Krishna's brother? Vishnu?

Tukesh: Krishna, Vishnu... Same guy. 

Me: So... Who is Krishna's brother? 

Tukesh: Krishna, Vishnu, Ram... all the same. But different. 

Me: R-i-i-i-i-i-ght. So... Who is Krishna's brother? 

Tukesh: Krishna doesn't have a brother! 

Me: So... the answer is "This is a trick question because Krishna was an only child with multiple personalities?" 

Tukesh: No. Krishna doesn't have a brother. 

Me: Umm... Yeah... Okay... So... Krishna doesn't have a brother. 

Tukesh: Krishna has a brother - his name is Balaram.
