Does anyone know

I’ve never seen it done. I text the link. Under the video there is a share button. Click it and a little window opens, you will see a link in a text box on the left. Text the person that link and as long as their phone can play youtube videos, it will open when they click it.

There are apps for iPhone, blackberry and android phones that allow you to share youtube videos but both the sender and receiver need to have the app.
