Barry it.
Q: Why did Joan Rivers die during throat surgery? A: Because her career as a comic was stuck, but no matter how he tried, the Dr. Couldn't pull a laugh out of her.
Doctor responds: "Heavy drug use, ma'am" Widow: "But doctor, my husband didn't use drugs!" Doctor: "I know, but I did"
When the Doctor changes the timeline, it's usually for a good reason.
Barry the dead!
