Revealing: Almost all the taxi cabs used across the show have the code 9Z72 on top. Obviously it is the same cab they use for every episode, they don't even bother changing the sign.

Continuity: In the 7th episode of Season 5, the scenes when the "Storm-Trooper" (actually, a robot) passes by the window do not match. The first time we see it, from the outside, as soon as he passes, Robin notices him and points towards him, but the second time, from the inside, she doesn't point at him.

Continuity: In the 7th episode of season 5, the scenes before Robin and Barney leave the diner vary depending on the angle. From outside we see that Robin fixes Barney's suit before they leave, but from the inside she doesn't.

Continuity: When Ted tells Robin that he loves her, Robin's hair jumps from behind to in front of her ear between shots.

Continuity: When Robin steps out of her front door to give Ted directions, she wraps her cardigan around herself. In the next shot the cardigan is instantly open, and she wraps it around herself again.

Continuity: When Marshall is on the phone to Barney, the green highlighter jumps back and forth from on the desk to on top of the open book.
