Although Lord Brittish is notoriously invulnerable to attack by conventional weapons, there is an easter egg that allows you to slay him. Firstly, when you are in your home (on Earth) at the beginning of the game, you must take the box of rat poison from atop the fridge and then place it upon the electric bread maker. This will produce a loaf of poisoned bread. Take this loaf and carry it with you all the way to Lord Brittish's castle. At the castle, enter the small kitchen (accessible from a hidden door in the banquet hall), where you will find a plate of bread on the table. Replace this bread with your poisoned loaf. Lord Brittish will immediately enter the kitchen and proceed to unwittingly eat the poisonous bread. Shortly after, he keels over and dies.
Despite numerous characters proclaiming that Britain once again welcomes the disabled and poor after the Avatar cleanses the shrine of compassion, only one character returns to the city from their exile - the one-armed miller.
The castle shown in the loading splash-screen for the game doesn't actually appear anywhere in the game itself.
In the graveyard annex in the city of Britain, there are two headstones side-by-side, one marked "Roful" (pronounced the same as "Rofl") and the other marked "Mao". Of course, ROFLMAO is chat-room slang for "Rolling on (the) floor, laughing my ass off!" Although this acronym is well known now, at the time of this game's development, the reference would've been more obscure. Also, another headstone in the graveyard reads "Lohl" (pronounced "LOL")
