Gaudi Afternoon (2001)
Carmen: [to Cassandra] It's no wonder you can never get a date - sexual confusion.
Hamilton: [about his date] You know I never would have guessed it.
Cassandra Reilly: Guessed what?
Hamilton: That she was a transexual
[Cassandra chokes on her drink]
Hamilton: Not that I'm judgemental mind you, people are all different - I'm bisexual for instance.
[She chokes again]
Hamilton: Oh I'm sorry, being Irish you must not be used to talking about bisexuals, let alone transvestities.
