When you're going out with some girl and come to find out her family has between 3-5 other similarly looking/shaped females of varying ages/height that you also want to be shagging.
BOY 1: "Dude, my new girl has a younger AND older sister that look just like her but even hotter! And her mom ain't too shabby, either."

BOY 2: "Yeah? That MILF I'm banging on the slide has three daughters that I'm planning to go all Matryoshka Principle on."

A big mission that unites people in purpose.

On May 25, 1961, in his address to Congress, President John F. Kennedy proposed the national goal of "landing a man on the Moon and returning him safely to the Earth" by the end of the 1960s. This goal was accomplished on the Apollo 11 mission, when astronauts Neil Armstrong and Buzz Aldrin landed on the Moon on July 20, 1969, later returning back to earth.

There is a great story of the janitor mopping the floor at the Space Station being asked what his job was in the organisation. His answer was: ‘I’m helping to put a man on the moon”.

This highlights the Apollo Program’s 'secret sauce' - a big mission or goal to unite people in purpose.

A big challenge aligns people under a common cause like nothing else can.
