In the fifth season of Chuck Lorre's hit CBS sitcom "The Big Bang Theory," audiences are presented with a very familiar situation: Sheldon Cooper (Jim Parsons) and his girlfriend Amy Farrah Fowler (Mayim Bialik) are fighting. This time, it's because one of Amy's academic papers is going to be published in a scientific journal — Amy is a neuroscientist, which Sheldon often directly tells her isn't as impressive as his work in theoretical physics — and Sheldon isn't sufficiently excited, disappointing Amy. After getting advice from his friends Penny (Kaley Cuoco) and Leonard Hofstadter (Johnny Galecki), Sheldon, accompanied by Penny, goes to a jewelry store to pick out a gift for Amy that he hopes will smooth things over. When he presents her with a tiara, Amy is so excited and so stunned that she basically forgets about her disappointment altogether.

According to Bialik, fans love talking to her about this episode,...
