After the Magic Castle I kept saying how happy I was! I couldn't help myself, I was, "happy as a clam" as I put it to one of my friends... so, of course I had to dig into the origin of that saying... occupational hazard:)
It seems the saying is meant to be, "happy as a clam at high water/high tide", which makes way more sense then just trying to figure out why clams would be the go-to happy reference. According to Phrases.org.uk the earliest citation however was actually, "happy as a clam" in The Harpe's Head - A Legend of Kentucky in 1833.
