Low Cow Joke and the JOKESTER (LES Yarrows)

She finishes telling the "Low Cow Joke" and sees her friend across the street. "John Curley!" she calls, "John Curley knows a joke-- he's the Jokester!" The Jokester! Why, we've been looking for the Jokester, and here he is in the flesh!
But oh no— It turns out John Curley is the Trickster not the Jokester! How awkward!
