The first time I heard the song "Walking in L.A." (1984, Missing Persons) I thought they were saying,
"Walking in a lake / Nobody walks in a lake"
And I found that puzzling. No one walks in the bottom of a lake, but if you go to the beach, you have to walk out to where it is deep enough to swim, usually, if it is a public access beach.
So it seemed inaccurate.
