Recurring characters
Nate Hartley as Oswald "Ozzie" Kepphart, a local power walker and a nerd who wears large glasses. He used to hate skateboarding but became a part-time skater, the first sport he did not quit after a day, and eventually became a skater, though not a very good one. He occasionally sticks his butt out as a rude gesture, which annoys Luther. When he skates, he flaps his arms as if he is attempting to fly.
David Ury as Donald "Don" Donaldson, the owner and proprietor of Don's Donuts, Zeke and Luther's favorite hangout. In the episode "Luther Leads", Luther realizes that Don is the only one that works at Don's Donuts, although he hires more people in later episodes.
Marianne Muellerleile as Dorothy Joanne "Nana" Waffles, Luther's grandmother. Nana lives in an apartment with her husband Carl. She often inspires Luther because he does not want to disappoint her loft view of him, and the boys often come to her aid when she is in trouble.
Abigail Mavity as Lisa Grubner, a young, geeky girl who has an overwhelming crush on Zeke. She lives in a pink dollhouse in her parents' driveway and is an avid flautist and tumbler. Her first appearance was in the episode "Donut Jockey".
Scott Beehner as Deputy Dingle, a bumbling police officer who is always onto Zeke and Luther's shenanigans, but is easily bribed by turkey jerky as seen in "Bro, Where's Our Car?". Although an officer, he is very stupid, and also can be strict.
Lawrence Mandley as Reginald "Jumpsuit" Johnson, Zeke and Luther's cranky ex-astronaut neighbor who commonly growls and has a gravity simulator in his garage. His nickname is because he wears a jumpsuit every day. He once called Luther a menace but made no comment about Zeke.
Ron Fassler as Dale Davis, a local television news reporter always on the scene of a big event.

Juliet Holland-Rose as Olivia Masterson (season 1). Formerly the olive girl for the "Langley Olives" company, she was once Zeke's next door neighbor and crush. She tried designing him a skater look in the episode "Cape Fear", but only for it to fail, mainly to a large cape that became a safety hazard. It is noted that she has a crush on Zeke. She did not know that he liked her back until the episode "Adventure Boy". She likes brave guys.
Andy Pessoa as Garrett "Stinky Cast" Delfino (seasons 1–2), a local boy who constantly wears the same sleeveless white shirts, jean shorts and trademark cast on his arm. He is Zeke and Luther's camera guy. He has the hugest crush on Ginger which Zeke uses as leverage to pay for Stinky Cast's videos.

He then proceeded to try to injure himself to get a new cast and succeeded, thus restoring his name.
