the Pharrell Grammy's moment is interesting because to the audience at large the robot personas are just robots so they are playing the characters, laughing along, but Thomas and Guy-Man do have actual families so they likely just wanted to thank them. I think that's sweet.
I remember the Grammy moments, Guy is such a shy and adorable robot, he probably wanted to hug Thomas really badly but he might have gotten too overwhelmed at that moment. The first two awards was the awkward handshake/fistbumb, but the Album of the Year award is where they both hugged it out like "We made it Thomas, we finally did it!"
I believe we Daft Punk Fans are lucky to have the freedom of choice. We can call ourselves whatever we want. But one thing is for sure, we who love Daft Punk and is subscribed to this channel can certainly be called "Dafters".
