None of the main characters have been given a last name. Lex and Presley refer to their principal as Principal Tedward, rather than his last name, implying Altoonisburg may not necessarily follow conventional western naming systems. In "Dog Wed-DING", Munchy is referred by Bardo as "Munchtopher, son of Tedward", similar to how people are named in Iceland (first name + dad's (or sometimes mom's) first name in genitive form + son (if boy) or dóttir (if girl)).
- When Presley found her birth certificate and realized her middle name was Wesley, she was shocked and repeats her first and middle name, completely omitting her last name.Presley: My middle name's Wesley? I'm Presley Wesley?
- Characters like Mr. Prusko or Mrs. Castillo, whose last names have been revealed, may be the rare cases of characters who have family names, like the handful of Icelanders who have inherited a family name.
- Or maybe they're transplants to Altoonisburg.
She was first confirmed by Alan to be at work in "Karaoke Kickoff". However, in episodes with nighttime scenes, such as "Room For Munchy", Presley and Fisher's mom still doesn't make an appearance. Due to the time from it was first confirmed that she was at work up to "Room For Munchy", it can't be possible that Presley and Fisher's mom's on a business trip. A military deployment is more likely, since deployments are on average between six to 12 months.
- Fisher wanted to sell his annoying noise machine to the military, implying that he has connections.
- Alan studied maritime law on a cruise ship, meaning Presley and Fisher's mom is most likely in the Coast Guard, Navy or Marines.
