-Dr. Don Shirley: So where did this "Tony the Lip" moniker come from?

-Tony Lip: It's not "Tony the Lip", it's "Tony Lip". One word. I got it when I was a kid 'cause my friends said I was the best bullshit artist in the Bronx.

-Dr. Don Shirley: It doesn't bother you that your friends - the people closest to you - consider you a liar?

-Tony Lip: Who said liar? I said bullshit artist!

-Dr. Don Shirley: And what's the difference?

-Tony Lip: 'Cause I don't lie! Ever! I'm just good at talkin' people into... y'know, doin' things they don't wanna do... By bullshittin' 'em.
