This one's pretty funny. In the episode of 7th Heaven where Annie's dad and Ginger are marrying, you know how that Veteran guy makes the reception dinner? Well, when they come home to it, you can plainly see a large bowl of salad in the corner closest to a large bookcase. Then, when Mary and Matt come home to it, after the family has left it untouched, you see the same salad in the middle of the table, and a roast in the salad's rightful spot! A dancing salad!
