Is flatulence in church a sin?

I let a substantial ripper loose in church last week which was so loud that it caused the minister to pause his preaching and look up to the audience for a moment. I honestly felt elated and held in my laughter for the next few minutes.

Shortly before my grandfather died, I was visiting him in the hospital and he asked me to come close to him. He whispered a final piece of advice to me which was "wherever you go, let your ass air flow" and then he tried to laugh but just ended up coughing. Right at that moment the nurses came and wheeled him away. He winked at me as he disappeared down the hall. That was the last time I ever saw him.

Ever since that day, I have believed there must have been something spiritual about that advice. But I can't quite put my finger on it. Perhaps you could pull it for me?
