What are the top movies in terms of quotability -- not measured by a single strong line, but (a) sheer volume of quotable lines, (b) how much the movie is actually quoted?

Based on our household, I would say three top movies are:

- Wizard of Oz
- A League of Their Own
- Monty Python and the Holy Grail

Caddyshack and Animal House are up there, but not at the level of these three. Gone With the Wind boils down to two-three strong quotes, only one of which I hear used much.

Looking at this list, I think I might be showing my age. Although my 10-year-old son is a strong partisan of Monty Python and the Holy Grail, and my daughter of A League of Their Own.

Any nominations?
