Quantum Leap, Season 3

Mary:
Who are you?

Fake Al:
Yin and yang, good and bad. God...

Sam:
...The Devil.

Fake Al:
In the flesh, so to speak.

Mary:
This isn't possible!

Sam:
Come on Al, tell me he's not real...

Al:
Uh...I...you...ah...he's real. Oh Sam, he's very real.

Mary:
What is happening?

Sam:
Why are you doing this?

Fake Al:
To put an end to your meddling. Who gave you the right to go bungling around in time, putting right what I made wrong?!

Sam:
I'm just trying to get home.

Fake Al:
Well you're not going to make it!

Al:
What's with Ebenezer there?

Sam:
He's ready to tear down the mission with his bare hands, Al; I think I'm making things worse.

Blake:
I know you. You're that jerk from the lobby.

Al:
I am the Ghost of Christmas Future. Whoo-haha!

Blake:
Please. The Ghost of Christmas Future wore a black cape. Jacob Marley had the chains.

Al:
She think's she's having her baby in an alien spaceship.

Al:
Shake your booty.

Al:
Don't do anything I wouldn't do. And if you do, take pictures.

Al:
It's not like you're lost in a mall - you're lost in time.

Sam:
Do you have to sneak up on me?

Al:
I'm sorry. What do you expect a hologram to do? Knock?

Sam:
John is gonna write my favorite song in the future.

Katie:
Your favorite song in the future? Well, sing it to me.

Al:
[to Sam] Just remember you have an ace in the hole... me.

Captain Galexy:
Im Afraid Captain Galaxy will have to go away for a while..we have time for one more letter..." {He reads a letter from Sam Beckett the boy asking about traveling through space/time; Galaxy explanation is just how the Adult Dr Sam Beckett does travel through time!]
