The film: Tom Cruise stars as the titular down-on-his-luck sports agent trying to salvage his career by capitalizing on the good hands of Rob Tidwell (Cuba Gooding Jr.), a wide receiver for the Arizona Cardinals.

The setup: Said by Tidwell to Maguire as Maguire frantically tries to keep Tidwell from switching to another agent. Actually, said might not be the right word. More like screamed back and forth over the telephone for nearly a minute.
