Mongo has poor Mario-fu

We were recently given a Nintendo Gamecube by perspicuity.  One of the games cymrullewes has for it is something called (I think) Mario Sunshine.  It seems to have a good solid implementation of the DSD instruction.

DSD is sort of like DWIM, but ... opposite.  It's the inverse of DWIM.  Functionally speaking, it's typically (and extensively, in Mario Sunshine) used basically like this:

1. Figure out what the player intended.
2. Do Something Different.
