Make That Putt| Guess Whose Talking on my YouTube channel

 @christophermore6844 on YouTube 

On some yet not all videos I recorded or uploaded to YouTube that are on my own profile @christophermore6844 I included a photo/picture/image in the lower right hand corner of the computer screen holding a yellow tool called a level, with a piece of paper attached, that says "Guess Whose Talking".

For most of 2023 I have other people tethered to my body that speak for me.  When I wrote on the piece of paper that I attached to the yellow level (bought on Hennepin Av in Minneapolis, MN U.S.A.) I was not sure of the proper grammar.  Guess Whose Talking or Guess Who Is Talking?
