Have you ever felt overwhelmed with happiness when looking at something beautiful? This man has. It's almost funny, but also captures a rare occasion when a person feels so intensely that he loses control.

The man who recorded this wrote: It was rainbowing for at least an hour on January 8th 2010. It was incredible. The camera could not capture the vivid intensity and brightness. Look into the mirror, look into your soul!

Also useful to practise some expressions of happiness.

Listen to a song composed from this viral video: Double Rainbow Song.

Whoa, that's a full rainbow all the way
Double rainbow, oh my God
It's a double rainbow all the way
Whoa, it is so intense
Whoa, man, whoa, whoa, whoa
Whoooa, ho ho ho, oh my god, oh my god, that- oh my god
Woooooh, oh my! Wow, Woooh, yeah, oh my god
Oh my god, look at that!
It's startin' to even look like a triple rainbow
Oh my god, it's full, oh
Double rainbow all the way across the sky
Oh my god. Oh my god
Oh God!

What does this mean?
Oh, oh my god. Oh, oh, God
It's so bright, oh my god, it's so bright and vivid
Oh, oh, oh, it's so beautiful!
[sobbing]
Oh my god. Oh my god. Oh my god.
Oh my god, it's a double complete rainbow
