Smallville, Season 5

Jack:
After 20 years, the man's still got a Hell of a knack for the guilt trip, doesn't he?

Clark:
Usually works 'cause he's right.

Jack:
Your father's always had some pretty high expectations of the people around him. He's the one man I never wanted to disappoint.

Clark:
You should try being his son. The thing I always try to remember is, no matter how much he lays on, he never expects more than he expects of himself.

Jack:
You think your dad will ever forgive me?

Clark:
Yeah. I've given him a lot of trial runs in the forgiveness arena.
