    John Thomas "J.T." Lambert 

     Alicia "Al" Lambert 

  • Badass Adorable: Much stronger than she looks.
  • Bratty Teenage Daughter: Throughout the show.
  • Character Development: The only character with a real development, actually, as she gradually evolves into a totally different person.
  • Cool Loser: Somewhat, in the beginning.
  • Cute Bruiser: When she was a tough girl in the early episodes, apparently able to beat up people older than her.
  • Daddy's Girl: Due to being Frank's only daughter.
  • Deadpan Snarker: Easily the snarkiest character on the show, after Dana.
  • Four-Temperament Ensemble: Choleric
  • Girliness Upgrade: Originally a tomboy but she becomes more feminine as time goes by. Although Al very much may have continued her interest in sports later, this is very much forgotten onscreen by midway through the series as Christine Lakin entered puberty and the producers wanted to take advantage of her physical attractiveness.
  • Hot-Blooded
  • Jerk with a Heart of Gold: She's hot-tempered, rude, and rebellious, but she does have a moral center. Although she continues to be self-assured in later episodes, the negative aspects were toned down somewhat in later seasons
  • Little Miss Badass: Especially in early seasons.
  • Masculine Girl, Feminine Boy: Masculine Girl to Mark's Feminine Boy.
  • Missing Mom
  • One of the Boys: Very much so in the early episodes, due to being the only daughter of a single father with two brothers & her interest in sports (as well as the apparent lack of girls-only teams in Port Washington).
  • Only Sane Woman: More evident when she gets out of her aggressive tomboy phase, in later seasons. Especially in her trio with Dana and Karen, she's by far the most normal and levelheaded. It's also lampshaded in season 6 that she's the only Lambert sibling who is not an idiot.
  • Raised by Dudes
  • She's All Grown Up: From a somewhat cute tomboyish pre-teen to a stunningly attractive young woman. Most male viewers consider her the hottest girl on the show.
  • She Cleans Up Nicely: And how. J.T. was even surprised when his friend Rich was attracted to her in one episode.
  • Tomboy and Girly Girl: Tomboy to Karen's Girly Girl. Before her Girliness Upgrade, anyway.
  • Tomboy with a Girly Streak
  • Tomboyish Name: Al is short for Alicia.
  • Took a Level in Kindness: She becomes much less aggressive in later seasons. She used to be openly hostile to Dana and Karen, but in later episodes she always hangs out with them.
  • Vitriolic Best Buds: With Karen and, to a lesser extent, Dana.
