The wheel. The printing press. Walking on the moon. And now this.

A Twitter user named Seth Schneider pulled off quite an accomplishment over the weekend: he managed to snap a selfie while giving himself a high-five.

Sorry, Donald, but this just proves America is already great again. Just look at the staggering numbers of likes and retweets. It's pretty surprising that the iPhone doesn't have some sort of feature that lets people do this with the ease of swiping on a mirror.

Schneider inspired legions of other people to try and follow in his footsteps.
