Smart as a tackPosted: February 1, 2019
This is an example of a perfectly formed malaphor. It is a congruent conflation (the best kind of malaphor, imho) of “smart as a whip” and “sharp as a tack”, both describing someone as highly intelligent. Smart and sharp are similar sounding words, and both idioms contain the “as a” words. Also, if you sit on a tack, it does smart, doesn’t it? The mashup is also heard in the Adam Sandler movie, “Big Daddy”. Here’s the clip:
