This may amuse you. I went to type “Here are my comments” (something I do fairly frequently), but mis-typed it as “Here are me comments”. Word correctly identifies this as incorrect grammar, with a green line under “are”. Right click, accept the suggestion, and “Here am me comments” is deemed perfectly acceptable… 
Even better, “I and I own comments here man” is also deemed fine!
I may explore this further – be afraid, be very afraid…
