13. "Tricks and Treats," Freaks and Geeks
Air Date: 10/30/99
"Tricks and Treats" occurs very early on in the series, when Lindsay (Linda Cardellini) is still straddling the line between her academic, buttoned-up lifestyle and becoming one of the Freaks. Her decision to ditch her usual Halloween mainstay of handing out candy at home and join the Freak gang for a fun night of vandalism and debauchery is pivotal in her transformation. Her brother and his friends learn that they're too old for actual trick-or-treating through a rough night of increasingly embarrassing events. It all ends with a rough realization by Mrs. Weir (Becky Ann Baker): her children aren't quite children anymore.
