Audio problem: When the woman catches Barney doing The Naked Man, she yells at him to get out. After Barney says "Just have to grab my suit, it's very expensive", she says "Get out!" twice. When she says it the second time, she quickly turns her head and her mouth doesn't seem to move with the audio. (00:19:10)
Continuity mistake: When they call Barney to find out if he succeeded with The Naked Man, the girl answers the phone. In that shot Barney's tie is curled up next to the shirt, but in the next shot, the tie lies on the shirt. (00:19:00)
Continuity mistake: When Lily is making her list she takes the lid off the pen twice. (00:09:00)
Chosen answer: In a flash forward scene in Season 8, it shows him with his first born: a daughter.
