“What are you chewing?”
“Apple seeds.”
“What’s the point in that?”
“They make you more intelligent.”
“Oh. Could you give me a couple then?”
“Sure. One pound per seed.”
“Hmm. OK. I’ll take five.”
After chewing for a while …
“You know, I could buy a lot of apples for a fiver …”
“See? The seeds are working already.”
