Out of Shape

Sometimes things just don't seem to fit together right.

Still, I WILL succeed in today's mission of getting a square peg into a round hole eventually! (note for pedants - the diagonal of the square is greater than the diameter of the circle. Note also that "round" indicates "circular", and both 2D shapes refer to the cross-sectional area of a "peg" with length at least twice the diameter of a circle completely encompassing the cross-section.).
