Birds of a Feather Stick Together!

But we are not birds, babe. We are beans!

Birds of a feather flock together is an English proverb which means that people who are similar to each other often spend time together. From this proverb, comes the idiom, Birds of a feather.This proverb has been in use since the 16th century and Plato had been said to have used the phrase in his dialogue with Socrates ,"The Republic". Plato was a classical Greek philosopher who lived around 428/427 BC – 348/347 BC. Now, I'd probably buy it if you had said that the idiom or proverb came from the Greek.
