Items usable on other players

So I sat down today to work on the long-missing support for items that can be used on other players (via curse.php) - only to find that the Wiki doesn't even have a list of such items! Arrrgh! Here are the ones I was able to come up with, what am I missing?

wang
brick
roll of toilet paper
heart necklace
cream pie
disintegrating sheet music
white candy heart
pink candy heart
orange candy heart
lavender candy heart
yellow candy heart
green candy heart
black candy heart
flavored foot massage oil
foam dart
personalized coffee mug

loaded serum blowgun

...technically, although there no longer a valid target for it, so don't bother.

snowball
jawbreaker

It would be awesome if there was some CLI command to use these all, by the way.
