I am bothered by one little detail.

Justin Dew is clearly not Carol Burnett.
Yet "he" never denies this, not once.
Go back and read the entire thread.
"I am not Carol Burnett", a critical denial, is NEVER stated, not even one time.

After carefully following the logic in this thread, in it's entirety, this can only leave one possibility:


Justin Dew is Orson Bean.
