I don't know who would win, but one thing is for sure, it would be either Kovalev or Froch or a draw.
I love the smell of my own farts. I always know from the way it came out how badly it is going to smell. Honestly, if it burns, its going to be vile. For me, half-cooked porridge oatlets, or undercooked potatoes, or that mixed-bean vinaigrette salad are winners, every time. Ever notice how a fart seems to stick to you for the first few seconds? I fart, then move off after a few seconds, then look back at the stragglers in the supermarket aisle that resemble stricken soldiers in a WW1 trench as my gas wreaks havoc.
Did you ever cup one? I farted into a jar once, screwed the lid shut and it was STILL THERE when I opened the jar the next morning.
