Characters from Andy Griffiths' Just...! series. If you're looking for the character sheet for What's with Andy?, see here.
An overly-creative pre-teen who gets on the nerves of everyone around him.
- Abhorrent Admirer: To Lisa.
- Accidental Pervert: In "The Last Jaffa" Andy crawls around the floor of a cinema trying to find a chocolate ball, which leads to him accidentally sticking his head up a dress.
- Annoying Younger Sibling: To Jen.
- Anti-Hero: Andy is a trickster, annoying, stupid, crazy, disgusting and outright shocking. Really, the only reason he's considered any kind of hero is because the stories are told from his point of view.
- Attractive Bent-Gender: Andy once trolled Jen by cross-dressing and imitating her up until the school dance. His disguise was so good Craig fell for him.
- Book Dumb: It was mentioned in one story that he only got one out of ten for spelling at school, and that it's actually a vast improvement.
- Class Clown: Tries to be this, but it's implied that his classmates find him just as irritating as his family does.
- Companion Cube: Andy is very attached to a rubber ducky. Said rubber ducky becomes the mascot for "Just Disgusting!".
- Dogged Nice Guy: Andy has the worst luck when it comes to impressing Lisa. She always gives him another chance, which he blows the very next time she appears.
- Everything's Better with Monkeys: Andy tries to crash Jen's birthday party dressed as a gorilla. To his dismay, he can't get out of the costume.
- Expy: Andy is Ferris Bueller, minus the charisma and intelligence needed to actually pull off his schemes.
- Laser-Guided Karma: While he manages to get on everyone's nerves, it turns out Andy can be completely outdone by children younger than himself, with his reputation preventing any adult from taking his side (and that's assuming they aren't just getting back at him).
- My God, What Have I Done?: In "Beat the Bomb!" Andy pranks some poor kid into believing he'd just won $500. The boy says his family could really use the money since his dad died. Out of guilt, Andy decides to give him the $500 prize money he'd just won.
- Naked People Are Funny: Andy has a habit of getting naked at the worst possible moment. Mr and Mrs Bainbridge are usually on the receiving end of it.
- Unsympathetic Comedy Protagonist: Due to a lack of any real foresight, Andy's schemes tend to backfire on him in the most spectacular ways possible. More often than not it's his own fault.
Andy's idiotic sidekick.
- Bumbling Sidekick: Any time Andy tries to get him in on one of his schemes, Danny ends up causing Andy a load of pain.
- Too Dumb to Live: Danny. At one point Andy was able to convince him that some jellybeans were "invisi-pills".
- With Friends Like These...: Andy and Danny are far from the best of friends. Andy only hangs out with Danny because he doesn't have any other friends. Danny only hangs out with Andy because he's too stupid to see that Andy's a bad influence.
Andy's one-sided crush.
- Nice Girl: Despite Andy making a fool of himself every chance he gets, Lisa never completely rebuffs him.
- Not So Different: Lisa isn't as pure as Andy builds her up to be. She challenges him to a marshmallow-eating competition in "Chubby Bubbies", admits that she enjoyed the bloodier and gorier version of "Kittens, Puppies and Ponies" and Lisa co-wrote the parody of Mac Beth with Andy and Danny.
- Prophecies Are Always Right: Apparently believes this, as she received a book on fortune-telling from Andy that he'd tampered with to tell her he was her ideal match. She fell for it.
- The One That Got Away: It's pretty much a given that Andy will never, ever, be able to woo Lisa.
Possibly the longest-suffering parents in the world.
- Butt-Monkey: Every story they're in has them both being pushed beyond their mental threshold.
- Not So Different: "Playing Dead" has Andy fake his death to avoid going to school. His parents decide to call his bluff and try to bury him in their backyard.
- Rage Breaking Point: In "Are We There Yet?" Andy's dad is pushed to the point where he dumps Andy out in the middle of nowhere in order to humble him.
- Take a Third Option: In both "Would You Rather...?" and "SHUT UP!" , Andy gives his parents an ultimatum. His mother is smart enough to know that doing this will disappoint Andy.
Andy's older sister.
- Alpha Bitch: She's got a popular boyfriend and has loads of friends, but is nasty to her younger brother. Justified on that last one.
- Aw, Look! They Really Do Love Each Other: In "A Terrible Christmas and a Crappy New Year", one of Andy's pranks ends up working in Jen's favour. Her response is to thank him for it, pretty much the only time they're not at each other's throats.
- Ax-Crazy: In "Mudmen" Sooty inexlicably tears off Andy's bathroom towel and shreds it up, before doing the same to his dad.
- Black Comedy Animal Cruelty: After Sooty literally eats Andy and Danny's homework, they put him through all sorts of hell to make him throw it up. This includes making the dog smoke cigarettes.
- Extreme Omnivore: As standard for a dog. He once literally ate Andy's homework.
Mr. & Mrs. Bainbridge
The uptight boss of Andy's father and his equally-uptight wife.
- The Comically Serious: They're not the least bit lively.
- Motor Mouth: Mr Bainbridge is very talkative, at least until Andy's antics come to their logical conclusion.
- Running Gag: Every book has at least one story involving them confronting Andy in the nude.
- Big Man on Campus: Has this reputation, as his presence at the school dance in "Copycat from Ballarat" was considered a focal point.
- Jerk Jock: He's threatened to beat up Andy every time they interact.
Andy, Danny and Lisa's new teacher.
- Cool Teacher: She's traveled to numerous countries and even worked in major films before becoming a schoolteacher.
- Hippie Teacher: She's traveled the world and isn't the least bit fazed by Andy's weirdness.
- The Lost Lenore: She's a widow. An unfortunate mountain-climbing accident forced to her subsist off her husband's corpse to survive.
