Too be honest it's a good write up, but not one I'd use.
It requires to many conceptual jumps by the audience.
It's to be honest a diferent sketch.
One where GWB gets matey with KJI becuase they're on the same wavelength (brain dead).
If you're pastiching a pre-exitising sketch you need to be very faithful, and quite respectful to the original.
Once it isn't a man complaining at a shop, it isn't the Parrot sketch.
Also GWB not being an idiot, has maybe a little irony value?
