A young couple went to the sea shore for a day to soak up the sunshine and relax. No sooner had they walked onto the sand, when a blonde in a bikini and carrying a mysterious black bag caught their eye. She walked up to everyone who was playing a radio, talked to them for a moment and then either smiled, nodded and walked away or reached into her bag, took money from them and handed them a package. "She's selling drugs!" the girl said to her boyfriend. "Why don't you try to find out for sure, then we'll call the police." The fellow advanced to where the blonde was standing, his boom box blaring rock music. The girl watched as the blonde approached him, talked for a moment and when the fellow shook his head, she smiled, nodded and walked away. The girl rapidly walked up to her boyfriend and said:"She was trying to sell you drugs, wasn't she?" "No," he replied, smiling. "She is a battery salesperson. She sells C cells by the sea shore."
