Hey, Mister ?

Are you calling me "Mister", Mr ?

Not Mr Mister

How can I help you, Mr …Richard …Castle?

I thought you were gonna say Richard Page

Don't make me laugh: you are a writer

He was too

He wrote songs, dude!

Do you want me to sing to you?

No, thanks, it just stopped raining

I got a pretty voice, you know

I don't doubt it

C'mon on, be a sport

Richard Lambourne?

I won't follow you there

Too high!

Richard the Lionheart
