Never had the chance to wrote it, but you can see how
GTO had a huge influence on this manga. You can see it in the drawings, in the characters' faces (the MC would have been perfect in GTO) and also on how the author does the paneling, by suddenly presenting an absurd and surprising picture with just a big "!?" (although, here it's just a "?" on page 14).
In fact, the beginning of this chapter reminds a bit oh how Uchiyamada was always thinking of the worst, like how he thought Onizuka was doing dirty things with his daughter.
I'm not saying that's bad or whatever, it's just interesting to see how much of an influence GTO had on the author. And it's not a bad one, mind you.
