英语笑话:业余工作

Part-time Job
When my son was a hign-school sophomore, he got a part-time job sacking groceries at a supermarket. He came home all smiles.
"How was your first day?" I asked.
"It was great, Dad," he replied. "I got to talk to some good-looking girls."
Since Stephen is not very talkative, I asked, "What did you say to them?"
"Do you prefer paper or plastic?"
