And that's how weekend was invented!

Once upon a time, there lived many organs in a busy body village. 

They were tired of working for the village head and went to the heart. 

Heart asked, “Hey guys! Welcome! Tell me your heart out”

They complained “Oh dear heart! Please save us. We are super tired. We can’t take it anymore. Brain gives us a lot of work. We work round the clock without any joy and celebration.”

Heart assured them to help and went to meet the head.

Heart said to the head, “Hey Bro! Wassup! All the organs have lost the spirit to work. Why do you give them so much work?”

Head said, “Da! What can I do? Our master has so much work to do. If we don’t accomplish that then who would?”

After some hard negotiation, they agreed to work for 5 days and enjoy for 2. That’s how the weekend was invented and everyone lived happily thereafter.
