English subject-verb agreement done wrong [Sound/Video]
for the intro of a presentation on the fossilized subject-verb agreement paradigm of some English L2 speakers I am looking for a video or sound file to demonstrate the issue. Speakers don't have to be shown or known, as the file only is used for introductory purposes. The idea is that the speaker does not use the third person "s" in verb conjugation in most if not all cases, but except from that shows high level English skills (doesn't have to be without accent or some minor mistakes).
So does anyone know any video or sound file I could use for this purpose?
Thanks in advance,
