An Orthodox Jewish couple are wondering what to get their son for his upcoming Barmitzvah. So when he gets home, they ask him:

So, David, what would you like for your Barmitzvah?

He replied, I would love a motorbike!

When David had left the room the Jewish couple talked about this amongst themselves. They had no idea what a motorbike was! So, they went down to their synagogue and told the Orthodox Rabbi that their son wanted a motorbike for his Barmitzvah but they didnt know what it was.

I have no idea! he said to the couples surprise. Youll have to ask the Reform Rabbi down the road.

So the couple walked down the road and asked the same question to the Reform Rabbi. But his reply was the same as the Orthodox Rabbi:

I dont know! Youll have to ask the ultra-mega Reform Rabbi further down the road.

So, the couple walked further down the road and found the ultra-mega Reform synagogue. They walked inside and said to the Rabbi there:

Our son wants a motorbike for his barmitzvah but we dont know what one is…can you help us?

And the ultra-mega Reform Rabbi replied, Woah, woah, woah, slow down a bit! First things first: whats a Barmitzvah?
