A video of an odd, swaying plant mystified the Internet this past weekend. Two clips posted to YouTube by user jethack show a fairly large leafy protrusion vigorously bouncing side-to-side, seemingly of its own accord.
It doesn't look like there's wind blowing any of the other leaves nearby, but a commenter speculated it's probably just a closed palmetto frond that can catch any slight breeze and go crazy. The video has prompted some pretty healthy debate on reddit as well, where it has received more than 1,200 up-votes.
The user wrote that the plant is near Hilton Head Island, S.C.
