Well, ok only 2 or 3 but still too far. When Sheldon thought he was going to die. "So this is how it's gonna end." was fine and done well but the falling down the stairs with Penny and farting was too far. It just didn't need to be there. One is a enough. Falling down the stairs at the end was kind of ridiculous. Overdone.
Shelbot was pretty cool and he certainly got that robot together real fast! I know there is a timelapse but still..wow! It was a good episode for the most part but had this aired in the first season it would be the beginning of the end because of its corniness. This show can do a bit better.
