- Name's the Same: Mikoto Suou shares both her first and last name with a completely unrelated character from a completely unrelated anime called K. It's downplayed slightly because their last names are usually romanized differently (the one from K is typically "Suoh", and the one from School Rumble is typically "Suou"), but not by much since in the end it's still the same name anyway and the spellings aren't universally accepted by fans of either series anyway.
- The Other Darrin:
- Karen was voiced by Yuka Nanri for season 1, replaced by MAKO for succeeding appearances.
- Jirou was voiced by Hirotaka Nagase for the first season, replaced by Makoto Tomita for succeeding appearances.
- Overtook the Manga: The second season ran out of content from its corresponding school term, resorting to several filler episodes and an open anime-original ending that is best forgotten.
- Portmanteau Series Nickname: "SukuRan"
- Same Content, Different Rating: The series has consistently gotten TV-PG to TV-14 ratings on YouTube, until about a little before midway of Second Semester, where that rating was bumped up to TV-MA for no discernible reason for all following episodes. And yes, the previous episodes do not appear to have had their rating changed in response to this, either. And no, the show's overall formula did not really change at all.
- What Could Have Been: Word of God says Nara was supposed to be the main character.
