A childhood belief about farting

when I was young I used to believe that underwear was a filter for farts. so then I thought that if I didn't wear any underwear they could smell worse. then I decided to play a joke on my brothers. so one day my brothers were in the living room watching TV. I decided not to wear any underwear, just my pants and I started running in circles and farting really hard and loud in the living room with my brothers in it so they could smell it. I had eaten a can of beans that day. And I kept saying, my farts are not filtered. but then, to my surprise, one of the farts came out wet and from that day on I always wore a pair.
