They say "Never meet your heroes" but in the case of Paul Rudd, that's one statement that doesn't ring true. He recently came to the rescue of a young fan of his after learning no one signed his yearbook—and now this sad story has a happy ending.

After learning that no one wanted to sign 12-year-old Brody Ridder's yearbook, Ant-Man himself decided to reach out to the young boy. His mom, Cassandra, wanted to bring awareness to childhood bullying, so she shared images of the blank yearbook on Facebook.

After older students at Brody's school learned of Brody's blank yearbook, they arranged for a bunch of students to sign sentiments for him. The news began to make headlines, and eventually made its way to Paul Rudd, who sent Brody a package with Marvel gear and a letter.

“That people would tell him no and deny him a signature, it just hurt my heart,” Cooper says.

Shortly after, Brody and Rudd shared a heartfelt FaceTime session and Rudd wrote him a hand-written letter that he'll undoubtedly cherish forever. (I mean come on, having a real-life superhero personally address something to you is inarguably cool.)

Cassandra shared the phone call on her Facebook page last month.

“It’s important to remember that even when life is tough that things get better. There are so many people that love you and think you’re the coolest kid there is―me being one of them! I can’t wait to see all the amazing things you’re going to accomplish,” Rudd wrote.

Rudd sent Brody an Ant-Man helmet, which he also signed: “To my good friend Brody, for when he takes on the world!”

Cassandra shared Rudd's care package on her Facebook and shared that now that they've developed a strong foundation for a real friendship, Brody and Rudd communicate regularly via text. (Cue "The Good Ones" by Gabby Barrett as a highlight reel of Paul Rudd's cutest moments plays over and over in my mind.)

At the end of the initial FaceTime call, Brody declared that Paul Rudd was his favorite superhero (clearly). Rudd's response? "You're mine."
