A couple lived near the ocean and used to walk
the beach a lot.
One summer they noticed a girl who was at the
beach pretty much every day.
She wasn't unusual, nor was the travel bag she
carried, except for one thing; she would approach
people who were sitting on the beach, glance
around furtively, then speak to them.
Generally the people would respond negatively
and she would wander off, but occasionally
someone would nod and there would be a quick
exchange of money and something she carried in
her bag. The couple assumed she was selling
drugs, and debated calling the cops, but since
they didn't know for sure they just continued to
watch her.
After a couple of weeks the wife said, "Honey,
have you ever noticed that she only goes up to
people with boom boxes and other electronic
devices?" He hadn't and said so.
Then she said, "Tomorrow I want you to get
a towel and our big radio and go lie out on the
beach. Then we can find out what she's really
doing."
Well, the plan went off without a hitch and the
wife was almost hopping up and down with
anticipation when she saw the girl talk to her
husband and then leave.
The man walked up the beach and met his
wife at the road. Well, is she selling drugs?"
she asked excitedly.
No, she's not," he said, enjoying this probably
more than he should have.
Well, what is it, then? What does she do?" his
wife fairly shrieked.
The man grinned and said, "She's a battery
salesperson."
