"Suddenly I feel like a round peg in a square hole" That is such an old-school saying that, unless if you have heard someone mentioned this back in the early 2000s, or heck, even the 1990s, most individuals nowadays don't even get the reference unless they really visualize what that means...God I love old-school humor, just leagues better compared to today's stall humor they push out to Gen Alpha guys/gals.
