Where and how did Tina Fey get that scar on her face by her mouth?
Tin Fey was in her front yard when a stranger approached her and slashed her face with a knife leaving her with the signature scar she still carries today. She was five years old when it happened.
She fell off her bike as a child.
I had heard she was attacked by a dog. I'm not positive, I heard what DavidO said also.
