Keeping this in consideration, where did expression happy as a clam come from?
The phrase most likely started as the longer phrase “happy as a clam at high tide,” and was popularized in the early 19th century, particularly in the northeastern United States. Clams can only be readily dug up by humans when the tide is low; in high water, they're almost impossible to find.
Secondly, why is a lark happy? The first of these similes dates from the late 1700s. The second alludes to the lark's beautiful, seemingly very happy, song. The third, from the early 1800s, alludes to the fact that clams can only be dug at low tide and therefore are safe at high tide; it is often shortened to happy as a clam.
Similarly one may ask, how do you know if a clam is happy?
In fact, those who keep them as pets cite only two signs to tell if they're happy: a mouth that is not “gaping” (a clam that opens too wide is under distress), and a mantle (or skin inside the shell) that receives frequent exposure.
Where does the saying the proof is in the pudding come from?
BEN ZIMMER: Well, the proof is in the pudding is a new twist on a very old proverb. The original version is the proof of the pudding is in the eating. And what it meant was that you had to try out food in order to know whether it was good. INSKEEP: Zimmer adds that the word pudding itself has changed.
