A young, newly engaged couple visits the woman's family for the holidays. After a rich, heavy meal, the young man becomes terribly gassy and badly needs to pass gas. But wary of etiquette, he holds it in as long as possible. After dessert, he can no longer withstand it and lets fly a quiet, silent, devastating fart. Embarrassed, he is about to excuse himself when suddenly, his future FIL yells, "Cinder!!"
Cinder, a gorgeous black lab, bows her head and moves away from the young man. He quickly realizes they think the dog is to blame and uses this to his advantage. Again, he passes gas and again, the FIL exclaims, "Cinder!" Cinder mopes away, tail between legs. The young fiancé believes it's worked...they all think it was the dog.
Finally, thinking he's in the clear, the young man releases a powerful burst.
Finally the FIL yells, "CINDER!! GET AWAY FROM THAT MAN BEFORE HE ****S ALL OVER YOU!!"
