Howard: Gentlemen, I am about to send a signal from this laptop through our local ISP, racing down fiber-optic cable at the speed of light to San Francisco, bouncing off a satellite in geosynchronous orbit to Lisbon, Portugal, where the data packets will be handed off to submerged transatlantic cables, terminating in Halifax, Nova Scotia, and transferred across the continent via microwave relays back to our ISP and the external receiver attached to this... (works successfully) lamp!
Sheldon: Leonard, don't take this the wrong way, but the day you win a Nobel Prize is the day I begin my research on the drag coefficient of tassels on flying carpets.
Leonard: (wanting to go to a science meeting) Sheldon, we have to do this.
Sheldon: (not wanting to go to a science meeting) No, we don't. We have to take in nourishment, expel waste and inhale enough oxygen to keep our cells from dying. Everything else is optional.
(Changing clothes in front of Penny while she is turning her body another way.)
Penny: Don't worry, I won't look.
Leonard: I know you won't. Why would you look? There's nothing to see. Not noth...
Penny: Sweetie, put the pants on!!
Howard takes a photo of Penny who has fallen asleep on him at Leonard's presentation. However, on the phone he uses, a Nokia N95, the camera is on the back but Howard faces the front towards him while taking the photo.
When Penny and Sheldon are walking up the stairs, Sheldon stops a short moment, but long enough for Penny to reach the next set of stairs. However, when the camera angle changes, Sheldon is next to Penny again and they are both walking up the next set of stairs at the same time.
The video Howard plays on YouTube is different from what actually happened, and not just the angle, but several minor differences that can easily be detected if you watch closely.

Sheldon: ...but Occam's razor would suggest that someone threw it out.
Though there is no long explanation of this, Occam's razor is a principle in which "the simplest explanation or strategy tends to be the best one".

(Penny is holding a bottle with a miniature city in it.)
Leonard: That's the Bottle City of Kandor.
Leonard explains this himself like this: Kandor was the capital city of the planet Krypton. It was miniaturized by Brainic before Krypton exploded and then rescued by Superman.
