Who Thought it?

I was reading Miles' blog about people eating animals and I just thought of something. Who was the first person to think of eating a cow? I mean, look at those creatures. They're filthy, dumb, disgusting animals. Who thought, "I wonder if that disease ridden parasite's muscles taste good? I think I'm gonna kill it and find out." That's sick and twisted. Now we know that it does indeed taste good, but the first guy to give it a shot? There had to be something wrong with him. The same goes for the first person to eat an egg. It popped out of a chicken's behind! Where did someone get the idea to crack it open and eat the unborn animal? Or a raw oyster? Or milk from a cow. Wow.
Those people can maybe be understood by hunger. Hungry people do desperate things. But there are a few other ideas that blow my mind. Smoking. Where did that come from? Why would anyone consider finding some weed, rolling it up, lighting it on fire, and sticking it in your mouth? That's so counter intuitive. Normally people try to keep hazardous substances away from their mouths. There are several other things, like drinking coffee and beer that I just don't understand how they got started. And I don't understand how anyone can stomach beer long enough to acquire a taste for it and get drunk. I had a non alcoholic beer once and it was nasty.
Some people just don't think like the rest of us. Some of these odd inventions are great. Things like chocolate with peanut butter and milk on cereal. These were odd ideas, but turned out great. Then we've got the sad things that we have to put up with in life like olives on food and meth. These people make our world an interesting place.
