This story may or may not be true, but it's funny either way.
The man paused the video to show barber what he wanted to look like. The barber thought the triangle was part of the style and shave two triangles onto his head.
he barber allegedly asked the customer if he wanted to keep the triangle.
Not sure what this meant, the client said yes.
If it's not a true story, I respect the lengths someone went to for the gag.
