Sheldon: Thank you for agreeing to see me, Agent Page.
Agent Page: Thank you for filing a complaint with my superior, Dr. Cooper. I understand you want to recant your statement about Howard Wolowitz.
Sheldon: Yes.
Agent Page: Was your statement untrue?
Sheldon: No.
Agent Page: Then I'm afraid you can't withdraw it.
Sheldon: I'm sorry. I don't recall you saying no backsies.
