In Sakigake!! Otokojuku, Heihachi Edajima picks up the phone and introduces
himself. As the other guy begins to introduce himself as well, Heihachi
Edajima starts giggling, as shown in the following image:

Is there any particular reason for why Heihachi Edajima starts laughing in
this precise moment?
