Centurion: What's this, then? "Romanes eunt domus"? People called Romanes, they go, the house?
Brian: It says, "Romans go home."
Centurion: No, it doesn't! What's the latin for "Roman"? Come on, come on !
Brian: Er, "Romanus"!
Centurion: Goes like?
Brian: Annus.
Centurion: Vocative plural of "Annus" is?
Brian: Er, "Anni"!
Centurion: "Romani"... [writes "Romani" over Brian's graffiti] "Eunt"? What is "eunt"?
Brian: "Go".
Centurion: Conjugate the verb, "to go"!
Brian: Er, "Ire." Er, "eo," "is," "it," "imus," "itis," "eunt."
