A woman, her husband and “the statue”

A woman was in bed with her lover when she heard her husband opening the front door.
‘Hurry,’ she said, ‘stand in the corner.’ She rubbed baby oil all over him, then dusted him with talcum powder. ‘Don’t move until I tell you,’ she said. ‘Pretend you’re a statue.’
‘What’s this?’ the husband inquired as he entered the room. ‘Oh, it’s a statue,’ she replied.
