1) Whenever he does this bellow a loud, shrill, off key, chorus of "It was only flatulation, I know".

2)If you do the cooking covert him to vegetarianism. Decaying plants smell better than decaying meat.

If he refuses or cheats on the diet 2) Catheterize his colon and funnel the gas into his face mask. Negative feed back will result. Of course there's always euthanasia. Lace his every meal with Fleet Phospho-Soda. He'll live out his last days in the can. (Putting him out of your misery).

cheers, Fortunato
