I use the phrase “Check it out,” often. Used it all of my life. We used it in the military, along with variations like, “Check this out.”
‘Check it out’ always meant, “Hey, look at this,” or “Notice this,” because it’s something special. In our house most recently, it’s been, “Check it out,” regarding something stupid Trump said/did, but also wildlife wandering through the yard — bucks in the day, skunks at night. Check it out.
My friend, a retired doctor, has more varied wildlife at his place. Although just a mile away, it seems further. He sends video of wildlife caught via a trail cam. Check it out, says his email subject line, and it’s a video two cubs nursing on mama bear a yard away from the camera. Or it’s a big bear scratching his back on a pine, another bear taking shelter from a rainstorm. Once in a while, it’s a cougar or fox taking a stroll.
John Cougar, who became John Cougar Mellencamp, who became John Mellencamp (the name he was given at birth), made a song of it in 1987. I saw him perform it in a soccer stadium in Germany the next year, a good show.
So, check it out.
