After Sheldon reveals an important plot point in a Harry Potter book Leonard was reading, Leonard has had enough and wants to move out. He decides to move to Penny's who is not thrilled though does her best to hide it. Sheldon seems fine without his former roommate...until Amy suggests herself as his new one. Meanwhile, Howard goes to Las Vegas with Bernadette so Raj has to stay with Howard's mom whose affair with the dentist is now over. Uh oh...This was another hilarious ep of "The Big Bang Theory" that I was bowled over for. I mean, seeing Penny and Amy's reactions to the new possible living arrangements was just sublime! And so was Sheldon's way of groveling! Oh, and how about Raj's reactions to the way Howard's mother treats him! I think I've said enough so on that note, I highly recommend "The Spoiler Alert Segmentation" ep of "The Big Bang Theory".
