I have a couple of stories.
1/
A brother always sat in the second row at the KH. He was a Maori.
One night, he lent over to pick up his Bible (or si book) of the floor, and he let out the largest rip I have ever heard. The chair was plastic which amplified the noise even more.
His young daughter which sat beside him turned back to see what everybody was doing, he without taking his eyes of the floor, put his hand on the top of his daughters' head and twisted it to face the front.
A brother was sitting beside me in the sixth row (nobody was sitting in between us and the 2nd row) along with the rest of us boys, whispered out loud "He sihnged my hair!"
The brother on the stage just stopped, looked up and smirked and then went on as nothing has happened.
2/
After a party at home, after everyone had left I let go a rip which was building up for sometime. The smell was that bad, it stunk out the backroom and the smell went through into the next two rooms. And I didn't even walked into them as yet!
3/
My father let rip one and it stunk that bad, everyone evacutated the room. Even the cat got up, looked at my father and shook it's head and walked out.
