I'm the most terrific liar you ever saw in your life - J. D. Salinger quote

I’m the most terrific liar you ever saw in your life. It’s awful. If I’m on my way to the store to buy a magazine, even, and somebody asks me where I’m going, I’m liable to say I’m going to the opera. It’s terrible.

J. D. Salinger

The Catcher in the Rye. Holden Caulfield in Chapter 3, after lying to the headmaster.
