A man who lived in a block of apartments thought it was raining and put his head out the window to check. As he did so a glass eye fell into his hand. He looked up to see where it came from in time to see a young woman looking down. 

"Is this yours?" he asked. 

She said, "Yes, could you bring it up?" and the man agreed. 

On arrival she was profuse in her thanks and offered the man a drink. As she was very attractive he agreed. Shortly afterwards she said, "I'm about to have dinner. There's plenty; would you like to join me?" 

He readily accepted her offer and both enjoyed a lovely meal. As the evening was drawing to a close the lady said, "I've had a marvelous evening. Would you like to stay the night?" 

The man hesitated then said, "Do you act like this with every man you meet?"

"No," she replied, "Only those who catch my eye."
