The "Latin" double plural indeed works only in the nominative, as Danny
suspected. The paradigms are different.

WOW!  That's a good one!  Hoodlum, hoodli, hoodlo, hoodlum, hoodlo;
hoodla, hoodlorum, hoodlis, hoodla, hoodlis!  ROTFL!

The latter form has always puzzled me.  _Viri_ is understandable, from
thinking it's an o-stem, but whence the second _i_ in _virii_?  This
would require an underlying singular form _**virius_.

Ha!  One of my favourite linguistic jokes is the "Latin" declension of
the word _bus_ `public carriage':

           Sing.  Plur.

Nom.       bus    bi
Gen.       bi     borum
Dat.       bo     bis
Acc.       bum    bos
Abl.       bo     bis

Sound cool when recited: "Bus, bi, bo, bum, bo; bi, borum, bis, bos,
Hey, that's a great .sig line!

There's indeed quite a number of *weird* applications of Latin
morphology to non-classical words in circulation.  As soon as a word
ends in _-us_, _-a_ or _-um_, you can be sure that someone tries to
decline it the Latin way.  I am not free of guilt, using _pizzae_ as
plural of _pizza_ in my high school days.

And I think I have already heard "reconstruted" singular forms such as
_Ferengus_ and _Quendus_.
