Yeah, that's the quote, but it's definately from the book... Lunge looks at the copy that those Japanese businessmen had (btw I was really disappointed he declined the karaoke). Later he's in the office with a Czech dictionary translating something and one of his cooworkers asks what he's doing. He says it's a quote from a picture book he thought was interesting.

I think Johan left a note with this on it or something... I kind of remember Tenma reading it and looking horrified.... but I could be wrong.
