"Gilmore Girls" has a knack for launching careers.
Melissa McCarthy, who played Sookie, and Milo Ventimiglia, who played Jess, both appeared on The CW series before finding widespread fame — but those well-known characters are far from the only celebrities on the show.
Eagle-eyed fans bingeing the show can find a surprising number of famous cameos, from young Victoria Justice to "Park and Recreation" star Nick Offerman.
Read on to look back on some of the show's celebrity cameos.
Chad Michael Murray played the popular kid.

Although best known for his starring role on "One Tree Hill," Chad Michael Murray had a memorable stint as Chilton's popular kid Tristan Dugray.
He harbored an intense crush on Rory, which manifested in him calling her "Mary" and picking fights with Dean. Sadly, he left for military school at the beginning of season two.
Adam Brody was (briefly) Lane's boyfriend.

Who could forget Lane's secret boyfriend, Dave Rygalski?
He pretended he was a Christian guitarist to get Mrs. Kim's approval and read the entire Bible front-to-back so he'd be able to take Lane to the prom.
Adam Brody's character eventually left for college in California so the actor could join the cast of "The OC" as Seth Cohen.
Victoria Justice was just a little girl when she appeared on the show.

Before she ever starred on "Victorious," Victoria Justice played a little girl at a "Lord of the Rings"-themed birthday party during season four.
Her character wasn't given a name, but she wore elf ears and told Sookie that her carrot "tastes like diapers."
Melora Hardin played a therapist.

Melora Hardin, best known as Jan on "The Office," played a therapist on "Gilmore Girls." The Gilmores set her up with Christopher at Friday night dinner.
She also counseled Lorelai to ask Luke to elope — and we all know what happened after that.
Arielle Kebbel played Dean's wife.

The "Aquamarine," "John Tucker Must Die," and "90210" actress played Dean's unlucky-in-love wife Lindsay.
Not only did Dean not appreciate the effort she went through to cook him dinner, but also he cheated on her emotionally and physically with Rory while she was in college.
Jane Lynch couldn't handle Emily Gilmore's antics.

You'd be forgiven for forgetting Lynch's brief cameo on "Gilmore Girls." She played a hospital nurse who quickly got sick of Emily's antics after Richard's heart attack during season one.
Danny Pudi's role was as a writer at Yale.

During a Young Voices of Journalism panel at Yale, Rory held her own against the verbose, opinionated young scholar.

The Independence Inn's most temperamental harpist, Drella, currently stars in "The Marvelous Mrs. Maisel," though we will always have a soft spot for her role in "The Lizzie McGuire Movie."
Borstein also played Emily Gilmore's stylist in later seasons of "Gilmore Girls."
Billy Burke briefly appeared as Lorelai's love interest.

The "Jessica Jones" star played Lucy, one of Rory's artsy college friends from season seven.
Unfortunately, due to boyfriend drama (really, Marty?), she didn't make too many appearances. Still, props to her for getting Rory to let loose and put streaks in her hair.
Bryce Johnson was Lorelai's young date.

Who can forget Lorelai's young date Paul? Bryce Johnson's character mostly served as a means to amp up the Lorelai-Luke tension, and as a clever punchline.
Fortunately, he was given a much meatier role on "Pretty Little Liars" as Detective Wilden.
Jon Hamm made a cameo on a terrible date

The "Mad Men" star had a cameo as Peyton Sanders on season three.
While the on-screen advertising executive could woo any woman on "Mad Men," he had a harder time impressing Lorelai Gilmore — and the pair had a terrible date.
Max Greenfield tried to start a club.
