When one uses the phrase bored as the Dickens, they are describing what it's like to be so bored that you are bored enough to write a bunch of famous fictional novels.
Person 1(the jester):"Hey you there are you bored too? What shall we do?"
Person 2 (the very bored very pretentious Prince):"Yes I'm very bored, bored as the Dickens. Charles Dickens that is..."
1:"GEEZ MAN! Now that's bored! What do you suppose we do about it?"
2: "I dunno cuz I'm not quite creative enough to write a bunch of novels about Christmas and ish..."
Long pause...
2: "Dont just stand there staring at me! I order you to start singing and dancing! and tell me a story in your songs too damnit!"
