Swimming carnival

[morsla]

There's a school swimming carnival happening in the pool across the street. A wisecracking teacher is making announcements over the PA system, treating the captive audience to his standup routine. Maybe it's just the acoustics, but I can't hear the roar of laughter from the crowd...

The thing that most confuses me is this: what kind of school names their houses Dragon, Demon and Sabre?

Edit: Sabre house has hacked their way to bloody victory over the demons and dragons that opposed them. Still not sure if the school is secretly controlled by gamers, metalheads, or both.
