we were eating dinnet at a member's house, and I had been holding one in for the whole time. We had just had a great spiritual thought, and my companion was saying the closing prayer. It got to the point that I felt like it'd be a silent one, so I carefully let it out. It definitely turned out not be silent. The worst part was is that it was quiet enough that I had reason to hope that it would pass unnoticed or unrecognized. I had thought I was safe when my companion continued the prayer without hesitation. 10 seconds passed and I thought I was in the clear, when as he said, "In the name of " he cracked and let out a little laugh. At that point everybody broke and it turned into a solid 30 seconds of laughing before he was able to finish the prayer. I never lived that one down..
