The club has members who enter by saying a password.
The man hides behind a bush to try to hear the password.
One member comes. The doorkeeper says "twelve". The member replies 6. The doorkeeper lets him in.
Another member comes. The doorkeeper says "six". The member replies 3. The doorkeeper lets him in.
Now the man thinks he knows the password and approaches the door. The doorkeeper says "eight". The member replies 4. The doorkeeper does not let him in.
