Surprised no one has mentioned (unless I missed it) the Blade Runner homages? "I've seen things you wouldn't believe" which I would have let pass if they hadn't followed it up with "Home again home again jiggedy jig."
...I feel ashamed that missed these quotes considering Blade Runner
is my favorite film of all time. When were they spoken?
He says I've seen things you wouldn't believe (or possibly a slight varient of it) during his speech to the "God". home again home again he says as the Tardis touched down at the end.
