I was watching "Something's gotta give" with Jack Nicholson and Diane Keaton and I couldn't help notice Jack Nicholson's scarf changing it's fold over and over on every scene. Of course I chuckled to myself.... I know some of these movie people have to know that the scarf is looking different on every scene. And I've heard they purposely do these flubbs. Can you think of any movies with bloopers?

they're called goofs by the way- or continuity errors or whatever- bloopers are outtakes from the film when someone screws up their lines.

On imdb they have lists of them. The Rocky Horror Picture Show has tonnes of them (I'm not sure whether they were intentional though) such as cables seen dragging a wheelchair around, a handbag changing positions on the ground several times etc.
