Smart Guy

T.J. is a boy genius who gets bumped up from the fourth grade to high school. T.J. tries to adjust to his new life, but he shares some classes with his 14 year-old brother Marcus, the school jock, and his clueless and self-absorbed 16 year-old sister Yvette.
Shout out to this show for featuring a father figure that wasn't an absolute buffoon, unlike most sitcoms of it's day. I watched this all the time when it ran on Disney Channel in the early 2000s, I've been watching some episodes on Disney+ and I'm surprised at how well it holds up.
