Brunch. Cat videos. Snapchat filters.

Of all the things millennials get excited about, nothing warms their hearts quite like watching the casts of their favorite TV shows and movies reunite -- especially when it's documented via social media.

Luckily for them, it seems like a new cast is always jumping on the reunion train. Here are some of our favorite throwback moments.

'Hart of Dixie'

Zoe, Lemon and Wade were spotted pretty far
Zoe, Lemon and Wade were spotted pretty far from their Bluebell comfort zones. Rachel Bilson, Jaime King and Wilson Bethel reunited at an ACLU benefit in Los Angeles on March 4, 2017. Bilson posted this photo on Instagram with the caption, #reunited. King also posted a silly photo of the trio and wrote, "The cast of #HartofDixie still act like a bunch of idiots when together. Wilson burped in my neck. Some things never change." (Credit: Rachel Bilson via Instagram)

'Fresh Prince of Bel-Air'

Everyone enjoys a little
Everyone enjoys a little "Fresh Prince of Bel-Air" throwback every now and then, especially when it involves a young Will Smith singing the sitcom's theme song. Unfortunately, this cast reunion didn't involve any "b-ball outside of the school" or other smooth rhymes (as far as we know). Alfonso Ribeiro, who played Carlton Banks, shared this photo of himself with his '90s TV family on Instagram on March 27, 2017. He paid tribute to his former TV dad, the late James Avery. "Wishing that James Avery was still with us to make this complete," Ribeiro wrote. (Credit: Alfonso Ribeiro via Instagram)

The cast of "Even Stevens" has had a few run-ins since the Disney Channel show went off the air, but the most recent was the first big cast reunion of 2016. Christy Carlson Romano, who played Ren Stevens on the series, shared a picture of herself with Brendan Rooney, her husband, and Tom Virtue who played her on-screen dad from 1999 to 2003.

As a wise coach once said, "A team is something you belong to, something you feel, something you have to earn." And once you've earned a spot on a team like the "Mighty Ducks," you're a member for life, apparently. The cast reunited in 2015, 20 years after "D2: The Mighty Ducks" premiered. And, because sometimes you can have your cake and eat it too, they actually formed a Flying V and posted it on Instagram. (Credit: redcrumbs via Instagram)

'The Little Rascals'

"The Little Rascals" aren't so little anymore, but they still know how to have fun. The cast gathered before the movie's 20th anniversary in 2014 to recreate some of its most iconic scenes, and a lot of them were really, really great. But their spot-on version of the movie poster takes the pickle -- err -- cake. Why haven't all our favorite childhood movies done this yet? (Credit: Blake McIver via Twitter)

'Mean Girls'

Playing with our emotions? That's so Regina George. Lindsay Lohan (Cady Heron) posted this photo with Tina Fey (Mrs. Norbury) to Instagram in August 2014, much to the delight of Plastics-wannabes everywhere. But then, like it was no big deal, she deleted it. (She's a life-ruiner. She ruins people's lives.) Two years later, Lohan continues to string us along, teasing a "Mean Girls" sequel. "I have been trying so hard to do 'Mean Girls 2.' . . . I've already written a treatment for it; it I just need a response," Lohan told CNN on Dec. 29, 2016. (Credit: Lindsay Lohan via Instagram)

Sarah Michelle Gellar may be known for being tough on vampires, but she's nice to living creatures. As if this 2014 photo wasn't warm and fuzzy enough, we'll have you know that Gellar reunited with her "Buffy" father-figure, Anthony Stewart Head, over Cool to be Kind bracelets to show her support for the organization he created to promote kindness to animals.
