13 Actors You Forgot Had Cameos On "Freaks And Geeks"

One of the best things about Freaks and Geeks is the abundance of secondary and minor characters who went on to have great careers of their own.

1. Lizzy Caplan

NBC / Via fanpop.com

Before she was rocking weaves made out of your mother's chest hair in Mean Girls, Caplan played Sara, one of McKinley's resident cool girls with a crush on Nick (who she manages to snag by the end of series).

Appeared in: "Pilot," "Beers and Weirs," "Tests and Breasts," and "Discos and Dragons."

2. Ben Foster

NBC / Via sitcomsonline.com

"Special," super-sweet Eli first popped up as Lindsay's kind-of-date to the homecoming dance, then as the most enthusiastic Three's Company fan ever.

Appeared in: "Pilot" and "Carded and Discarded."

3. Allen Covert

NBC / Via buzzfeed.com

It might seem like this guy only appears in Happy Madison movies, but he also played the nearly no-nonsense clerk who was hesitant to sell Sam, Neal, and Bill a keg of non-alcoholic beer.

4. Rashida Jones

After watching her in Parks and Recreation, it's hard to imagine Jones being a badass. As Kim's friend Karen, though, she's basically ready to kick Sam's ass if he doesn't move it in Freaks.

Look, he doesn't make the rules at the Iron Horse, he just plays by them.

When you need a fake ID, who better to go to than Toby, Millie's "kind of scary" cousin?

We're not sure if LaBeouf's Herbert got to be the school mascot again once his arm healed, but we like to think so.

9. Leslie Mann

Not long after she married Apatow, the hilarious Mann appeared as MicKinley teacher, and love of Bill's life, Miss Foote.

10. Alexander Gould

Imagine little Shane Botwin of Weeds, freaking potheads out long before his own mom started selling the stuff.

11. David Krumholtz

It's too bad we didn't get to see more of Barry, Neal's cool older brother and Lindsay's one-time paramour — he was such a babe.

Appeared in: "Noshing and Moshing"

12. Samaire Armstrong

NBC / Via becuo.com

Anna from The O.C. isn't the only of Samaire's offbeat, high school roles — she appeared in a couple episodes of Freaks as a hippie.

13. Ben Stiller

One of a handful of uncredited guest stars, Stiller popped up in the series' penultimate episode as a Secret Service agent going through a vocational identity crisis.
