One of the more memorable lines from Indiana Jones and the Last Crusade. Here is a portion of the screenplay:

HENRY and INDY mount their horses. Henry turns back to his son.

HENRY: What did you find, Junior?

INDY: Junior?! Dad...

SALLAH: Please...What does it always mean, this...this "Junior?"

HENRY: That's his name. Henry Jones, Junior.

INDY: I like Indiana.

HENRY: We named the dog Indiana.

BRODY: May we go home now, please?

SALLAH (to INDY): The dog!? (laughs) You are named after the dog...

INDY (embarrassed): I've got a lot of fond memories of that dog.

It becomes even more funny when you consider that 'Indiana' was the name of George Lucas' dog (an Alaskan malamute according to some), who was with him while he wrote the script for the first Indiana Jones movie. In early versions of the script the main character was named Indiana Smith, a play on Steve McQueens character Nevada Smith, from the movie with the same name.
