I’m not the sharpest tack in the drawerPosted: January 20, 2020
The speaker was not feeling well and mentioned to someone about her mental acuity for the day. This is an incongruent conflation (opposite meanings) of “not the sharpest knife in the drawer” (not very smart) and “sharp as a tack” (intelligent and quick thinking). As everyone knows, there are many expressions out there describing the dull witted individual, and these expressions are often mixed up. I have posted several of these mashups, including “not the brightest tool in the shed”, https://malaphors.com/2013/06/24/not-the-brightest-tool-in-the-shed/, “not the sharpest bulb in the shed”, https://malaphors.com/2017/08/03/not-the-sharpest-bulb-in-the-shed/, and “not the brightest knife in the drawer”, https://malaphors.com/2018/02/14/hes-not-the-brightest-knife-in-the-drawer/, to name just a few. A big thanks to Yvonne Stam for admitting she uttered this one and realizing it was a malaphor.
