The thing you need to understand about Andrew WK is that he's a performance artist. He's playing a character. The difference between him and most other performance artists is that his art output is 100% good-time no-thinking-required fun. The other difference between him and most other performance artists is that he's a household name. There's a reason for this.
Andrew WK the "real" man is a sparkling personality tied to a huge and clever wit, which is the engine operating a massive circular saw that cuts your "he's not taking himself seriously" argument's legs off.
So, with that in mind. In this video he's not being pitifully wacky a la Robin Williams; he just has no idea how to describe what's appearing on the green-screen behind him, but is giving the job all of his good-natured energy nonetheless.
Death to wacky. Death to intellectual doldrums. Long live Andrew WK.
