A woman goes to her boyfriend's parents' house for dinner. This is her first time meeting the family and she is very nervous. They all sit down and begin eating a fine meal. The woman is beginning to feel a little discomfort, thanks to her nervousness and the broccoli casserole. The gas pains are almost making her eyes water. Left with no other choice, she decides to relieve herself a bit and lets out a dainty little fart. It wasn't loud, but everyone at the table heard the poot. Before she even had a chance to be embarrassed, her boyfriend's father looked over at the dog that had been snoozing at the women's feet, and said in a rather stern voice, "Ginger!" The woman thought, "This is great!" and a big smile came across her face. A couple minutes later, she was beginning to feel the pain again. This time, she didn't hesitate. She let a much louder and longer fart rip. The father again looked at the dog and yelled, "Dammit, Ginger!" Once again the woman smiled and thought, "Yes!" A few minutes later the woman had to let another one rip. This time she didn't even think about it. She let rip a fart that rivaled a train whistle blowing. Again, the father looked at the dog with disgust and yelled, "Dammit, Ginger, get away from her before she shits on you!"
