What should I do if my grandfather farted all over everything?

He's farted all over the house. He eats dumplings with beer or nuts, then sits down in the living room and starts farting almost nonstop. Or, conversely, he'll just sit there and grunt, and you can tell he's about to explode, and then, like, explodes like a nuclear bomb, it'll make your ears ring! He farts and he likes it all farted through. To keep the stink down, when he sits in the room with a bucket of dumplings and bottles of beer, my grandmother closes the door and stuffs all the cracks with rags to stop the smell, but it doesn't help much. The concentration of his farts in the apartment, especially in the living room, becomes incredibly high. Once in the winter, when the windows were sealed, he farted so much that he started choking, but since he was too lazy to get up, he threw a beer bottle at the window, knocking it out, and sat there, drinking beer into his bottomless belly. Every month, grandma buys him 10 pairs of underwear and mends the old ones because they burn through and rip from his farts. Maybe there's some kind of pill to stop him from farting.

P.S.

And today he remembered his old trick: he lies down on the bed, presses his arse against the wall, and farts against it. There's already a crack in the wall, and where he's farting, there's a brown stain and crumbling plaster!!! He lies there for about 20 minutes and starts swearing from the pressure on his belly, and then he yells "heeeeeeeeee" and lets out an extremely powerful blast against the wall. You can hear the vibrations going through the wall!!
