(possible Zork II spoilers)
Giving other verbs "all" can lead to interesting results. In Zork II
(whatever version is installed in the Zork Anthology; btw, did anyone else
find it interesting that the .DAT files for Zorks I-III in this package
are all exactly the same length?), when you are trapped in the bank's cube
(I unfortunately forgot how to do this puzzle -- if I ever really knew),
and the gnome comes in and wants a treasure, and you type "give all to
gnome" it accepts the input. It'll scroll through your list of items...
matchbook: "Why would anyone want to put that in a safe-deposit box?"
...until reaching the first treasure, which the gnome will put in the box
and let you out. Your player is moved to the room containing the cube.
AND you keep giving things to the gnome. AND if you hit another treasure,
he puts it in the box and lets you out of the cube you're already out of,
and your player is moved to the current room.
And so on and so on.
