From 11:00PM PDT on Friday, July 1 until 5:00AM PDT on Saturday, July 2, the Shmoop engineering elves will be making tweaks and improvements to the site. That means Shmoop will be unavailable for use during that time. Thanks for your patience!
Mmm. Twinkies. Wait, where were we? Oh, that's right. Number 2. Charlie tells us a story about rats, pleasurable rewards, and electric shock. It's a very interesting experiment if you can put the whole animal-testing thing aside.
