In a special documentary on BBC One, Kirsty Young interviewed Sir David Attenborough about his life, career and travels to celebrate him turning 90.
And while watching the programme - featuring footage from many of his documentaries from over the decades - viewers couldn't help getting teary eyed.
This bit was especially emotional.
And there were some seriously beautiful clips.
The documentary made everyone laugh as well.
We even got to see some animations.
ICYMI, here's a gorilla talking about Sir David. What more could you possibly want?
The documentary was basically the perfect way to celebrate everyone's favourite naturalist.
We second that. Happy birthday Sir David!
