In the movie GREASE, Sandy is having a sleepover at Jan's house. 26 minutes and 40 seconds into the movie, Jan hands Sandy the only bottle of wine. Then at 27:56, Jan has the bottle of wine in her hands, along with her Twinkie (which incidentally come in a paper bag with the wine, without a wrapper). As the scene changes back and forth between Sandy and Jan, the bottle of wine jumps back and forth as well. When the scene is on Sandy, she has the wine; when the scene is on Jan, she has the wine. This occurs several times.
