"My faithful student, Jon Pertwee,

I'm pleased with your concern for the fate of the Earth, but you know, just enjoy life and all that. Your head is filled with your dirty romance novels, so go to ponyville, prepare for the Summer Solstice, make some friends there, and well, you know the drill.

Just go and…Have a nice life.

- Yours truly, Princess David Tennant

P.S. Under no circumstances must you eat any ponyville pears."

These are the words that Jon Pertwee, faithful student to Princess David Tennant, reads, to his horror and chagrin.

An MLP-style parody-celebration for the Doctor's 51st anniversary.
