"Isn't there another 'prodigal?' Something like the Progigal Son?"
"Prodigal. Prodigal Son."
"No, that's different."
"Think there's only one Prodigal Son."
"No, the Progigal Son is a good thing. You'd say, 'The Progigal Son has returned!' and proceed to give him gifts and camels. See? Good. Prodigal is a negative word, meaning wasteful and lavish. See? Not good."
"Um, while that's an interesting take on it, that's not exactly how it goes. The Prodigal Son was lavish and wasteful - that's why he came back. The point is that he returned home and his father welcomed him, despite his waste."
"And, he got calf, not a camel. "
"Huh. Bummer for him."
