Well, my spec is that 4x13 is a HP/Who crossover where the Doctor is a house elf... in a bird cage. Martha ditches her cute jacket from S&J for a drab soldier's uniform and then becomes a door to door bible salesman. Jack is locked in a basement for a year where he can never have sex (so not possible, right?) The Master goes straight for a Rose look alike and then does music theatre on a navel carrier that floats in the sky.

How 'm doin'
