Okay... I have to admit, this episode actually amused me! This show never blows me away, but this episode actually had me chuckling a little bit.
Leonard has an epiphany about his research. He shares it with Sheldon, who loves the idea and immediately helps Leonard with it. The two of them write a paper and post it online to see what others think. Overwhelmingly, everybody thinks the paper is really innovative and original. Then, one anonymous person writes a mean message. Sheldon responds, feeding the troll, and the anonymous person keeps tearing Leonard and Sheldon down. Eventually, the troll actually video calls Sheldon, who is scared to answer. The two of them then decide to stand up for themselves, and they call the troll back. Turns out, it's Stephen Hawking! He thought their paper was very good, but he just wanted to mess with them.
First of all, I liked the fact that Leonard and Sheldon were a team here. There are lots of episodes that show one or both of them being annoyed with the other, or just in general they tend to tear each other down a lot. In this episode, they presented a united front, and I appreciated that. I was especially fond of the way that Leonard was nervous to share his idea with Sheldon, because he obviously respects Sheldon's intellect. Sheldon's support meant a lot to him. There was a funny recurring joke where Sheldon and Leonard called each other "Mr. Innovative" and "Mr. Original" or whatever else the online comments were saying about them. Howard would join in, and look to Raj to finish the improv, but Raj had nothing. So, that made me smile. Also, I do like it when Stephen Hawking comes on this show. I mean, I know it's probably beneath his dignity or whatever, but I'm a sucker for stupid celebrity cameos when they're done right.
