But out of all the "coming home" videos that have gone viral, a new one may be the most creative.
Master Sgt. Joseph Martel recently returned to his home in Germany a month earlier than expected, and he surprised his son, Justin, at a high school football game by dressing up as a member of the opposing team. During a meeting on the field, Joseph took off his helmet and revealed his true identity.
You might want to have a box of tissues nearby as you watch this video:
Justin was interviewed after the game, and it's clear that he was absolutely shocked by the surprise.
"I had no idea what was going to happen," Justin says. "And all of a sudden he was just there."
