Holy Grail, scene 16, take 47.
Arthur: We are but simple travellers. We seek the enchanter who lives beyond...
Tall knight: Atchee!
Arthur: Bless you.
Tall knight: Atchee! Atchee!
Arthur: I am not going to bless you twice.
Tall knight: If you do not wish to appease us, we demand a robbery.
Arthur: I am sorry, did you say shrubbery?
Tall knight: No, we want you to give us a robbery.
Arthur: Well, I can't give you a robbery.
Tall knight: Atchee! Then you shall not pass.
Arthur: But no one can give you a robbery. It's impossible!
Tall knight: You still can't pass.
Arthur: You 're crazy. A robbery is an action. It is something you do, not something you can give. It is not an object.
Tall knight: Atchee! A robbery or you shall be killed!
Arthur: Well, I can rob you, if you are sure that is what you want.
Tall knight: Atchee! Yes!
Arthur and his knights rob the Knights Who Say 'Atchee', and continue their way.
