Wrong assocation. Gas from plants is nonsmelling and there is alot of it. Meat will produce foul smelling gas, and my guess is from sulfur containing amino acids. That would be taurine, cysteine, and methionine, all of which orginate from cysteine. I remember the commercial, because I had a few problems like that at one time in my life. Appendix rupter feals like gas pain. I have had gas so bad I could not move, because it was so painful.
Ok fuckn nuts I am going to hook up my D drive!
