(The Root) -- So, wrestler and actor Dwayne Johnson (aka The Rock) is a big guy. We know that, but should you ever forget it, his Instagram account is full of pictures of him lifting weights and looking superhuman.

Also amazing are his Throwback Thursday pictures (on Thursdays, folks on social media share old pictures of themselves with the hashtag #tbt). There have only been two so far, but this week I've come to notice that The Rock was apparently a full-grown adult from the moment of his birth.

Seriously, look at these pictures:

Above is The Rock looking like he's getting ready for a hot date with high school senior Shannon, the one everyone was in love with ... AT AGE 4.

Here he is at the supposed age of 15. Who looks like this at 15?? He looks like he just finished a shift on a car-assembly line and is getting fed up with his kids because they keep taking pictures of him, and he just wants to kick back with a brew and watch the game.

Beyond that, we get to see a picture of a young Dwayne with his young father, who is apparently the person we should thank for the wonder that is The Rock.

And I'll just end this with this picture of a couple scars on Johnson's shoulder and his explanation of how they got there. Do with that what you will.
