Goof: When Penny and Leonard are at the gun range, Leonard shoots himself in the foot. On a 9mm pistol, the safety is off when the safety switch is facing horizontal along with the barrel of the weapon. The safety was never taken off, indicated by the red dot that is shown once the safety is off.
As indicated by the music in the background, the episode of Doctor Who being watched by Leonard, Sheldon, Penny, and Amy is "Silence in the Library".
When Leonard returns from a date with Penny and interrupts Sheldon's taping, the wide shot shows him closing the door behind him. After Sheldon says "Take 47" and the view cuts back to a close-up of Leonard, the door is now partially open.
During Sheldon's Fun with Flags segments, you can see the apartment flag from "The Staircase Implementation" behind him.
