There's something I've always wondered: why are clams happy in America?

And is this happy clam a shellfish or a cult member?

The expression is totally American and originated in about the 1830's
in New England. The original is often quoted as "Happy as clams at
high tide" or similar. That's when it's difficult to dig them up and
eat them!

I also experimented with extra canopy strings (I had to buy about 4,000
feet of red yarn to replace a lost string, so have plenty spare). They
were for ever getting trapped in the canopy and even when free weren't
that useful. Anyone need 3,900 feet of red yarn?
