If it hurts to laugh, this video is painful to watch:

[capri0mni]

Made with extra-normal's movie maker site, with generates computer voices and computer animation from text, which is why the voices are so stilted.

It is closed captioned, but there is no full transcript. The scene depicts a thirty-something woman (the sign language interpreter) and a middle-aged man (the college biology professor) in a classroom.

There are three points in the video when the dialog goes silent. During these periods, there are a sequence of random dance moves and flailing hands, which is a clueless Hearing person's attempt to imitate ASL.
