You have to go directly to "The Making of..." part in the special features. It's cute, but that's not what I am talking about.
About halfway through, you will come to a part where Jemaine is doing some flying stunt or something and he starts swinging upside down. That is funny, but still not what I am talking about.
When he lands he makes the cutest laugh/honking sound and has the most amazing smile you have ever seen. It's the scene that the screen cap that looks like he just got out of the shower comes from. I watched it over and over. OH, the joy of it.
Go...now...do... How pushy am I? Nah, I'm just excited for you
Oh yes! I saw it and I was elated! It's just too adorable, I completely agree. It's the sweetest, most ungarded smile in the world.
