Irregular Plurals

You know the sort of thing - one mouse, two mice; one man, two men; one house, two hice. Someone, American I think, maintained the plural of hippopotamus should be hippopotamice.

I have discoverd some others:

One swan, two swine;
One Beagle, two Biggles;
One lass, two lice;
One loaf, two life;
One salmon, two salmen;
One spat, two spit;
One shot, two ****.

I will gratefully receive other examples.
