Good catch. I didn't notice the inaccuracy in their numbering instruction(s).

Nice answers... I am less thrilled by puzzles that have a multitude of possible answers, preferring puzzles with unique or at least limited answers (crossword puzzles come to mind). A puzzle with a myriad of answers can make for good posting material, but somehow seems inelegant.

Refrigerator Air (5190 google hits)
Refrigerator War (9 google hits....similar to the cola war)

How about RewRite RepoRteR? It garners 29 hits on a Google search. Of course it pales in comparison to the 3990 for "refrigerator car"

I'm sure we could come up with some definitions for such beauties as RefRain RecoRdeR and RegRet pReseRveR also...
