Yup, this is what I've always seen when moving into Strangerville- the whole Welcome Wagon is possessed, then sometime shortly after the MiB's come and confiscate your refrigerator. I never noticed that they put a strange fruit in the fridge, I'll have to check that out next time! I always wondered why the MiB's did such a seemingly random thing.
When moving into Strangerville, hold off on buying a nice refrigerator- the MiB's pay you when they take it, but only half of what it costs.
