Diet Dr. Pepper tastes more like pissing me off

If Diet Dr. Pepper tastes just like regular Dr. Pepper, WHY HAVE REGULAR DR. PEPPER. I can't imagine that there is a huge market for a product that has extra calories and sodium. If there is no taste difference then what seperates them other than real sugar or a substitute? Look, if Dr Pepper really thinks Diet DP tastes like regular DP then they need to put their High Fructose Sugar Syrup Water where their mouth is and stop making Fat Dr. Pepper. And don't tell me that the crap in Diet soda causes cancer. I'm not saying it doesn't, but seriously everthing causes cancer now. The person in a tanning bed with a ciggarette in their mouth and a cell phone next to their head can't bitch about drinking Diet Soda. BUT BUT BUT, it causes cancer in lab rats. EVERYTHING CAUSES CANCER IN LAB RATS! Air, water, and I am sure being in a lab causes cancer in lab rats. Hell, being a lab rat causes cancer in lab rats. We need to find a more suitabe animal to do tests on. We should use Cockroaches, because they are hearty little guys. If it causes cancer in Cockroaches, I wouldn't do it, that's for damn sure. If a species known to live without it's head gets for several days gets cancer, watch out cause you know that is some serious stuff. And you will notice heavy use of the word SODA, that's right I still won't say pop and my recent trip home only confirmed the truth of it all. SODA NOW, SODA FOREVER.
