need hands to throw

From the newsgroup:  slash'em lychanthrope character could throw
while in wolf form.  That came straight from nethack; any animal capable
of manipulating an object--possibly with its mouth--could throw things.
Now hands are required.  This doesn't require free hands, although it
probably should; it's kind of tough to imagine making a competent throw
while your hands are stuck to a cursed two-handed weapon.
