Origin of Phrases - H
Happy as a clam
Meaning: To be very satisfied.
Example: A cold beer, some peace and quite, and I am happy as a clam.
Origin: Clams like to lay in mud. Claim diggers wade through the muddy water and use a specialized metal rack that has netting on the back to comb through the mud looking for the clams. The clams get caught in the netting.
Clam diggers are only able to catch clams at low tide. If the tide is high, the water is too deep to wade into and clams were safe from their hunters.
The phrase was originally "Happy as a clam at high tide."
