If you could go back in time

[LTR12101B]

And say one thing, to one person, at a critical moment, what would it be:

eg.

JFK: "Duck!"
John Lennon: "Don't open the door"
Gary Kildall: "Don't play golf today"

 

[The-poacher]

Tony Blair:Thank F*ck U Lost

 

[PC-GUY]

I would say something but someone would get mad.
