Ghost of a flea

...the original name of the character and the famous first line of the first book are quite similar to one found in episode 7 of Monty Python's Flying Circus. This is a transcript of the narration compared to the first line of "Harry Potter and the Philosopher's Stone":

"It was a day like any other and Mr. and Mrs. Samuel Brainsample were a perfectly ordinary couple, leading perfectly ordinary lives - the sort of people to whom nothing extraordinary ever happened, and not the kind of people to be the center of one the most astounding incidents in the history of mankind. . .so let's forget about them and follow instead the destiny of this man. . .Harold Potter, gardener and tax official."

"Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you'd expect to be involved in anything strange or mysterious. . ."
