I would not quite recommend this. I thought the teacher was going to call him gay. It was kind of a funny punchline. I admit that I'm pretty confused as to why this wasn't just used with the Cyaniade And Happiness characters. Well, they're not really characters, but you get the idea. Later submissions of theirs were submitted here.
I guess it just made little sense to me. The animation here wasn't bad. It just seemed pointless. It's fine for a single joke. I'd just wish for a straight (no pun intended) adaptation with the stick figures.
