Oh people. Let me tell you how to make your farts stink.
Eat an onion.....RAW. Take just a few bites like you're eating an apple....then wait for the magic. You will experience many hours of pure shtank.
Nah, I eat a dozen raw onions every week. The only time I fart is when I awake.
I wake up, fart, then go for coffee, but it has nothing to do with onions. I would fart anyway and the coffee is hardly negotiable, unless you are carrying a gun, then we might negotiate. I will warn you, however, I also have a fairly substantial weapon within reach of my pillow and I will still fart.
You are warned.
Now if we want to talk about farts, instead of poop being green, then let us start another thread.
