I'm not much of one for energy bars, and I don't think I've ever had a Clif Bar before, but I just bought a Cool Mint Chocolate Clif Bar on a whim and let me tell you: Wow. It's basically a giant oatmealy crunchy Thin Mint. I realized that as soon as I cracked the wrapper, it smells so good. And apparently it has a little caffeine in it.
Get one. Then do what I'm doing and go on Amazon Prime and get two dozen.
