A man walks into a pharmacy and asks for a pack of
condoms. As soon as
he has paid for them, he starts laughing and walks out.
The next day, the same
performance, with the man walking out laughing, fit to
burst. The chemist
thinks this odd and asks his assistant, if the man
returns, to follow him.
Sure enough, he comes into the store the next day,
repeating his actions
once more. The assistant duly follows. Half an hour
later, he returns.
"So did you follow him?"
"I did."
"And...where did he go?"
"Over to your house..."
