Who doesn't love a good surprise?

It can change the way the recipient remembers a certain day forever, which is why when these surprise videos are shared, they go viral!

For retiring Massachusetts police officer Duane Ledoux, the last day on the job, after serving with the Southbridge Police Department for more than 30 girls, was bittersweet.

When he makes his final radio call, he hears an unexpected voice on the other end. Ledoux's reaction will warm your heart.

The police department doesn't go straight to the surprise, instead they build it up, and luckily there's two separate videos to capture this precious moment.

First, Police Chief Shane Woodson spends a minute thanking Ledoux for his years of service and wishes him the best on the rest of his journey.

It's apparent in the video that Ledoux is already emotional after the chief's speech.

"I thank you," Ledoux says, pausing for a few seconds. "Too much to say, but thank you, and everybody in my family, everyone who I have served with, and to my boys." He then sniffles, and croaks out, "It's time to go home."

Ledoux probably thought the final radio call was over, until he hears another voice on the other end of the line.

The retiree's son, Nate, flew across the country to honor his dad's service during the final radio call, which the department refers to as a "final code five."

"It is my sincere pleasure to announce that ... after 32-and-a-half years of service, my father, Southbridge Police Officer Duane Ledoux, is retiring and has given his final code five," Nate says. "It is my honor to acknowledge this code five ..."

By this point, Ledoux figures out who is speaking, and looks at the camera, shocked, before he gets emotional once again.

Nate continues, "to set free a man who has sacrificed so much of his time for all of us, so that he may spend the rest of his life discovering new craft beer, exploring this beautiful country and, most important of all, chasing glory. Officer Ledoux, badge number 1041, dad, you are officially code five."

When the radio turns off, Ledoux shakes his head in disbelief and says, "He did come home."
