C-Span video if you prefer that over the written testimony: https://www.youtube.com/watch?v=Fd-_VDYit3U
1. A laugh track
2. An inset with a sign language interpreter
3. An imaginary friendship with a low budget meta commentator, like Mystery Science Theater 3000
The video version landed differently for me than the written testimony (it's the same person authoring both). I felt when speaking he emphasized the impact better than it came through in writing.
