A - 'Go to hell, you steaming bag of putrescent cockslime! You are a disgrace to the shit heap of humanity! The best part of that bloated, greasy bag of puss you call a body got flushed down the shitter when you were five! You ugly, cunting pile of rotten manure!'
B - 'Good show, by Jove! Such an charming adventure into the art of literary profanitation. Fuck you too!'
