Avishai, join the club!
When I was about 7 or 8 we had our book study at the house next door. On metal chairs. One night I felt a fart about to come out so I just let it slip, thinking I'd do it discreetly. I didn't. It was a big fast blast o' gas and sounded like someone dropping big marbles on that metal chair. Fortunately it was a pretty cool group of country folk and we all just had a good laugh about it and then continued the book study.
Odor experiences? Worst one had to be when my stepdad was a guest speaker at another cong. He planted us on the front row (groan!). Well, it seems that at a previous meeting some family had sat on that row and they had a kid who couldn't control his bladder and had pissed on one of the chairs. I and my mom had smelled it immediately, but didn't think much of it. Apparently, others did and complained. So partways into the WT study the conductor announced "we seem to have an odor problem on the front row..." and my family had to get up and move right there in front of everyone.
