Who would win a fight between Mary Poppins and Nanny McPhee?

[Essex Boy]

The gloves are off. Remember they've got hatpins and they know how to use them.
I see an endless running battle round the English shires with cute upper-middle-class kids in sailor suits used as cannon fodder.

(I tried to set up a poll but it wouldn't work.)

A double homicide would be best, of course, but as long as it's a bloodbath to the death, everyone wins.

Nanny McPhee would blast that Poppins bitch across the room.

Nanny McPhee and Mary Poppins would team up and fight the real enemy!
