This is NOT alright alright alright!

A Reddit user recently shared a photo of their great-great-grandfather, who bares an almost eerie resemblance to "Interstellar" star Matthew McConaughey.

And basically everyone cannot get over how similar they look.

The top comment on the photo read, "That's what I love about people in old photographs, man. I get older, they stay the same age," referencing one of the 46-year-old actor's most well-known lines in his breakout movie, "Dazed and Confused."

While the jury's still out on whether McConaughey is a time and space traveller, the resemblance to the great-great-grandather is surprising given the actor's ability to dramatically alter his own look for roles in recent years. After dropping a shocking amount of weight for his role in 2013's "Dallas Buyers Club," he was spotted last year rocking a balding head and major dad bod for the film, "Gold."

Whether or not McConaughey is the reincarnation of someone’s great-great-grandfather, we can all agree that he's wise beyond his years.
