I'm looking for a story where a vastly superior alien civilization "invades" United Earth space but instead of attacking, they surrender, much to the surprise of the assembled Earth military and dignitaries who were expecting total war or annihilation.
This is what I remember from the story:
A meeting takes place, where two representatives of the vastly superior invading fleet meet with the "Earth Alliance" top brass.
The Earth representatives are assembled; they're nervous and apprehensive. Then these two "Mutt and Jeff" type of characters, one tall and skinny, the other short and fat(?), approach the assembled human big shots. The humans have never seen anything like them.
Before the Earth Admiral can say anything, the aliens surrender to the forces of Earth. Throughout the exchange, Mutt and Jeff talk to the earthlings in normal, almost unconcerned tones and show a remarkably hilarious relaxed and amused demeanor.
Mutt and Jeff then say something like: "We'll have our diplomats contact your diplomats to arrange for adequate documentation, technology transfers and other things customarily done in such cases etc".
The Earth rep just blinks. Then one of the aliens adds that of course, they expect Earth Military occupation forces on their capital planet as soon as Earth can manage, or something to that effect.
All this comes to a surprise to all the humans there.
Formalities concluded, Mutt and Jeff turn around and walk back to whence they came, maybe talking among themselves like two Sunday strollers enjoying a walk in a park. The story ends shortly thereafter.
I don't recall where I've read this, an anthology perhaps - but I do remember that it was a very entertaining little story; been trying to fish it out for a re-read for some time now, but forgot where in my library the darn thing is.
