I have 2 things that I have simply never been able to figure out....
1- Why does a fart smell worse when it emerges from underwater? (Like if you are sitting in a bath or hot tub & rip one, it smells worse than if you had let'er rip on dry land.) What's the deal with that?
2- Yawning. What the hell? Is there a reason that seeing someone else yawn instantly causes a domino effect around the room? There simply must be a reason for this, but for the life of me, I can't figure it out...
