Other mistake: In the flashback where Gael is playing a guitar and singing a song, the chords on the guitar change, but his fingers do not move at all. He is playing the same chord the whole time.
How I Met Everyone Else - S3-E5
Other mistake: In the scene where Barney is describing The Vicky Mendoza Diagonal of The Hot-Crazy Scale, his words describe her getting hotter, (i.e. lost ten pounds) not less crazy. On the diagram shown, she goes down in craziness, not up in hotness.
Other mistake: When Barney shows Marshall the video of a dog pooping on a baby, he puts in the CD upside down.
Suggested correction: Lots of blank CDs that you can buy do not have labels on the top and therefore are just shiny on top (like they are on the bottom).
Not true. He points the writing at the camera and puts it writing side down.
Other mistake: Right before Barney gets hit by the bus, he's on the sidewalk. To the right there is a One Way sign pointing right, but the bus hits him driving left. The bus would have been driving the wrong way on a one way street.
Suggested correction: Not only is this not a mistake (it wouldn't be the first vehicle going the wrong way down a one way street), but we even see Barney looking in the direction of where the vehicles should be coming from and assume himself to be safe. Had the bus not been going the wrong way, Barney would have seen it coming and not been hit.
This is irrelevant. The mistake is that the bus is going the wrong way on a one - way street. While people do break the law like this, a bus driver certainly wouldn't.
