The Grinch: [cheerfully to his own reflection in the mirror] And a very good morning to you, Mr. Grinch.
The Grinch's Reflection: [infuriated] Oh, it is, is it?
The Grinch: Well, it seems so... sort of.
The Grinch's Reflection: I see nothing to whistle about. You must be out of your head, no doubt. I think the time has come for thee to repeat the Grinch's oath with me.
The Grinch, The Grinch's Reflection: [in unison] A Grinch is unhelpful, unfriendly, unkind.
The Grinch's Reflection: With ungracious thoughts...
The Grinch: ...in an unhealthy mind.
The Grinch's Reflection: A Grinch is uncheerful, uncouth and unclean. Now say this together!
The Grinch, The Grinch's Reflection: I'm frightfully mean! My eyes are both shifty. My fingers are thrifty.
The Grinch: My mouth will not smile.
The Grinch's Reflection: Not half of an inch.
The Grinch: I'm a Grinch.
The Grinch's Reflection: I... am a Grinch.
The Grinch: I'm a Grinch!
The Grinch's Reflection: That's my boy. Now go out and prove it!
