I know you're concerned about disappointing me, but I want you to take comfort from the knowledge that my expectations of you are very low.

There isn't enough chamomile tea in the world to quell the rage in my heart.

— The rumors of your demise were unfounded.
— Sorry to disappoint you.

The only thing people are good for is disappointment.

I'm a constant disappointment to my own father and I've learned to live with it.

— I've disappointed you.
— That's good, that's a good deduction, yeah.
— Don't make people into heroes, John. Heroes don't exist, and if they did, I wouldn't be one of them.

You want me to shake hands with you in hell? I shall not disappoint you.
