So what is it like to go back in time and talk to your 12-year-old self? An actor and video maker did just that - well sort of.
Jeremiah McDonald recorded an interview 20 years ago, during a time when there was no internet and gas was a lot cheaper, for his future self. And this year, he made another video, which answered some of the younger McDonald's questions and posed new ones.
He then cut up the two videos, remarkably making it a flawless back-and-forth conversation between the two. In addition to a touch of humor, this viral video is one of the most clever ideas we've seen.
It has nearly 5.5 million views in five days. Pretty good ratio, huh?
