From The Lion King:
Scar: Why! If it isn't my big brother descending from on high to mingle with the commoners.
Scar: Well, as far as brains go, I got the lion's share. But, when it comes to brute strength...I'm afraid I'm at the shallow end of the gene pool.
Scar: Must have slipped my mind.
Zazu: Yes, well, as slippery as your mind is, as the king's brother, you should have been first in line!
Scar: Well, I was first in line... until the little hairball was born.
Simba: Hey Uncle Scar! Guess what!
Simba: Hey, Uncle Scar? When I'm king, what'll that make you?
Scar: A monkey's uncle.
Simba: Come on, Uncle Scar.
Scar: Simba, Simba, I'm only looking out for the well-being of my favorite nephew.
Simba: Yeah, right, I'm your only nephew.
Simba: Hey, Uncle Scar, will I like the surprise?
Mufasa: Scar! Brother! Help me!
Nala: Scar.
Pumbaa: Who's got a scar?
Nala: No, no, no. It's his uncle.
Timon: The monkey's his uncle?
Nala: No! Simba's gone back to challenge his uncle to take his place as king.
Timon and Pumbaa: Ohhh.
Timon: Uh. We're going to fight your uncle... for this?
Scar: Oh, must it all end in violence? I'd hate to be responsible for the death of a family member. Wouldn't you agree, Simba?
Simba: You don't deserve to live.
Scar: But, Simba, I am...ah...family.
Scar: What are you going to do? You wouldn't kill your own Uncle?
