Something to understand, for those who might have just seen some youtube videos of him being goofy, is that he's an actor. The guy on camera doing stupid stuff is a stage persona. It's an intentionally cultivated image and media persona to get as many video views as possible.
I sort of see him as one possible aspect of the low/medium budget TV production stuff which is common in his home city, Vancouver BC. People who've met and worked with him in person report that he's a much more normal, calm, rational individual off screen.
I won't judge him for being goofy on camera because it's hard to make a living as a working actor. For every person who gets a job in a vancouver-produced TV drama that might last 2 or 3 seasons, there's dozens more people who are working as restaurant servers while trying to get their big break.
