How I Met Everyone Else - S3-E5
Continuity mistake: During the flashback in which Barney recounts the story of how he and Ted met (which was previously shown in the pilot episode of the series), there is a green circular plaque (that reads "Winner of the Queen Cup") on the wall in the background which wasn't present in the pilot episode. Also, Barney's left arm is in different positions than it was in the pilot.
Suggested correction: Many people buy another toothbrush to take on trips and since they were supposed to be going away, they probably decided to use them at home, as if this was their trip.
The whole point of the mistake is they say they have always shared a toothbrush. So why would they use separate on a trip?
