BARKING UP THE WRONG TREE
People can bark up the wrong tree, too, even though people don't usually bark. When people bark up the wrong tree, it means they are chasing after the wrong idea, or maybe they are going about something in the wrong way. They might also be following a false lead or blaming the wrong person for something.
The thing I don't like about this phrase is that it makes dogs look stupid, but mostly it's hound dogs that seem to bark up the wrong trees, so I guess that's okay because hounds can be kind of dumb anyway. Well, at least that's my opinion.
TO GO TO POT
Nowadays people mostly mean that something has gotten worse or has been ruined when they say it went to pot. This is called a metaphorical meaning, but cooking meat in a pot is a literal meaning.
Some amphoras were very fancy, with scenes from history or mythology painted on them. And there were amphoras of different sizes, from 12 inches to 5 feet tall. The Romans used one size of amphora as a unit of measurement, which was a volume of one cubic foot.
Archeologists like amphoras because they are often found in old shipwrecks, and sometimes their contents are still okay, which is pretty amazing, and the archeologists can learn interesting things about ancient people.
