Testing with his friend Frank

Walter decided to introduce his new invention to his friend Frank.

Frank was 46, a computer technician and a little overweight. He also had a preference for young girls, especially those in bathing suits. So he called him.

In the late afternoon, Frank pulls up in front of Walters house and quickly gets out of his car. He's not sure what's so important that Walter asked him to come over immediately. However, there was a sense of urgency in Walter's voice Frank hadn't heard before so he didn't argue and came straight over. Wiping some sweat off his brow, Frank quickly rings the doorbell and waits. "Oh second!" He hears Walter's voice call from inside.
The door opens a moment later.
