She Nudges Her Friend And Neither Of Them Can Stop Laughing
One nudge turned into a giggle fit. Two girls shoulder to shoulder, laughing so hard they were bending over. They kept trying to stop and couldn’t.
About this scene
Two friends walking together on a sidewalk, mid-afternoon. The flash happens at their shared sight line. One of them elbows the other in the ribs. They both see it at the exact same moment. The laugh starts simultaneously and lasts almost thirty seconds. Neither of them recovers. They keep walking but at half-pace and they have to stop twice because they're laughing too hard to walk. They are still laughing about it when they reach the corner.
What to watch for
The synchronized laugh is rare. Most pairs have a delay of at least a half-second between reactions. These two see it at the exact same moment and the laugh ignites simultaneously. The first stop happens about ten seconds in when one of them is doubled over. The second stop is when the other one needs to wipe her eyes. They eventually compose themselves enough to keep walking but you can hear them giggling on the audio for the rest of the clip.
