It's so great that we get to cheer for loaded Celtics teams and Miami is left cheering for one-trick ponies, punks and doofuses [sic].
Not sure why the [sic] is there ... I spelled doofuses correctly.
I believe the plural is doofi.

Not according to Merriam-Webster's Collegiate Dictionary, Eleventh Edition, though I'd be happy to admit I'm wrong if it's been changed since then (though I imagine that, even if "doofi" is now acceptable, "doofuses" would continue to be an acceptable plural form).
