I first heard a version of this quote as a U.S. Marine Corps quote.

I wonder if its origins are different than that.

I did a quick search and it seemed to still point to a military origin.

Dang! That's from 1985. That's true even today! Maybe all generations feel that way? And we just rediscover it in our own way?

Your grandma looks like she's seen some shit.

Huh, TIL I can still read cursive

Buddy of mine got this for me on a magnet as a birthday gift over 20 years ago from a Spencer's Gifts. I still have the magnet (would post a pic but currently traveling) and the words have been etched into my brain. I even had it as my Skype for Business status at one point.

Grandmas are so dang powerful

Vintage 1980 or earlier - multiple people had signs like this by their desks at my first job.

This quote is attributed to many different people, I read it was Edward R Murrows, or Mother Teresa, or Slick Rick or some Chech philosopher. It’s crazy how it has been relevant for so long.

brain autocorrected the title to "mowing the lawn at grandma's", and it almost still made sense.
