Not strictly on topic, but Digitalis' new avatar, coupled with the Lexiconians’ mission to show us the error of our ways reminded me of this:
LEXICONIAN: What's this, then? Lexicones Eunt Domus'? 'People called Lexicons they go the house'?
DIGITALIS: It-- it says, 'Lexiconians, go home'.
LEXICONIAN: No, it doesn't. What's Latin for 'Lexiconian'? Come on!
DIGITALIS: Aah!
LEXICONIAN: Come on!
DIGITALIS: 'L….Lexiconus'?
LEXICONIAN: Goes like...?
DIGITALIS: 'Anus'?
LEXICONIAN: Vocative plural of 'anus' is...?
DIGITALIS: Eh. 'Ani'?
LEXICONIAN: 'Lexiconi'. 'Eunt'? What is 'eunt'?
DIGITALIS: 'Go'. Let--
LEXICONIAN: Conjugate the verb 'to go'.
DIGITALIS: Uh. 'Ire'. Uh, 'eo'. 'Is'. 'It'. 'Imus'. 'Itis'. 'Eunt'.
LEXICONIAN: So 'eunt' is...?
DIGITALIS: Ah, huh, third person plural, uh, present indicative. Uh, 'they go'.
LEXICONIAN: But 'Lexiconians, go home' is an order, so you must use the...?
DIGITALIS: The... imperative!
LEXICONIAN: Which is...?
DIGITALIS: Umm! Oh. Oh. Um, 'i'. 'I'!
LEXICONIAN: How many Lexiconians?
DIGITALIS: Ah! 'I'-- Plural. Plural. 'Ite'. 'Ite'.
LEXICONIAN: 'Ite'.
DIGITALIS: Ah. Eh.
LEXICONIAN: 'Domus'?
DIGITALIS: Eh.
LEXICONIAN: Nominative?
DIGITALIS: Oh.
LEXICONIAN: 'Go home'? This is motion towards. Isn't it, boy?
DIGITALIS: Ah. Ah, dative, sir! Ahh! No, not dative! Not the dative, sir! No! Ah! Oh, the... accusative! Accusative! Ah! 'Domum', sir! 'Ad domum'! Ah! Oooh! Ah!
LEXICONIAN: Except that 'domus' takes the...?
DIGITALIS: The locative, sir!
LEXICONIAN: Which is...?!
DIGITALIS: 'Domum'.
LEXICONIAN: 'Domum'.
DIGITALIS: Aaah! Ah.
LEXICONIAN: 'Um'. Understand?
DIGITALIS: Yes, sir.
LEXICONIAN: Now, write that out a hundred times.
DIGITALIS: Yes, sir. Thank you, sir. Hail Insane Power, sir.
LEXICONIAN: Hail Insane Power. If it's not done by sunrise, I'll cut your balls off.
DIGITALIS: Oh, thank you, sir. Thank you, sir. Hail Insane Power and everything, sir!
