Well, I say "most stupid way", but we all know he isn't serious.
What I wonder is whether he's only making a joking, or poking fun at people who want to learn Japanese.

He's clearly joking... >.>
I found the video quite funny

4 people gave him a Like, and 4 a Don't like.
In general it's odd, people giving "Don't like's".
But I don't know why you would do it with this.
