Leather Goddesses of Phobos

1. In version 50, at Laboratory, you can EMPTY CAGE, allowing you to get the rubber hose without participating in the mad scientist's experiment.
2. In version 50, you can SIT or STAND ON STOOL when it is in the barge and you are on the dock. You can then send the barge away, leaving you on a stool that isn't there. While you're in this condition, DROP ALL says, "I don't see what you're referring to."
3. In version 50, if you get on the first slab as the gorilla while your body is still tied down, then you can't get back up.
4. In version 50, you can put the stool in the cage and then stand on it, but when you get off the stool you're still outside the cage.
5. In version 50, if you're holding the sheet at Bedroom, you can TIE SHEET TO BED without dropping it. You can go anywhere carrying it, but anywhere you drop it the room description says, "A sheet is tied to the bed.", and if you untie it the room description says, "The bed is unmade, with the sheet lying half on the floor." The rope behaves similarly, but if you untie it you get the same "unmade bed" message, as if the rope were still a sheet.
6. In version 50, if you are carrying the jar of lotion and say PUT ALL ON something, then when it gets to the jar it uses up the lotion. This is annoying if you're using the tray or stool to carry stuff. The same thing happens in all versions if, for example, you're carrying the jar on the tray and you EMPTY TRAY ONTO STOOL.
7. In version 50, you can STAIN things with a "can of black sain", even if you emptied it before using the machine on it.
8. In version 50, trying to put a non-empty container in the machine says only one thing can fit, but you can put things in or on something that's in the machine. Running the machine then leaves its contents empty.
9. In version 50, it's possible to enter the tree hole carrying the trellis. Just push Trent/Tiffany into the hole.
10. In version 50, if you're in the barge or the raft, you can EMPTY it, and you're told each item is dropped, but everything stays in the same place.
11. In version 50, while you're sitting on the toilet, any movement command responds, "You're not going anywhere until you get out of the toilet."
12. In version 50, although you're told the Sultan's spouse "pulls you down onto the furs," STAND claims, "You are already standing."
13. In version 50, WHERE AM I always answers with a "the", such as "You're in the Joe's Bar." or "You're in the Cleveland."
14. In version 50, while you're the gorilla, EAT MY BODY produces, "As you try, your body slaps you across the face. "Really, we hardly know each other.""
15. In version 50, trying to put the lip balm on your lips a second time while wearing it responds, "You'll have to remove the stick of lip balm first."
16. In version 50, it's possible to get a message like "Trent trots over to you." while you're both sitting on the stallion.
17. In versions 50 and 59, using the word EACH by itself as an object, as in GET EACH, produces the response, "[You used the word "other" in a way that I don't understand.]"
18. In the Solid Gold version only, COUNT FINGERS says, "Two, as usual." Earlier versions give the right answer.
19. In version 59 and up, after you've removed the lip balm from your lips, EXAMINE LIPS makes it reappear.
20. In all versions, trying to UNCOVER a person besides yourself causes a serious error. It addresses an invalid object, which Infocom's interpreters seem not to notice. Most other interpreters have a problem with it; some display garbage, others lock up, and some exit with a fatal error.
21. In all versions, if, playing as a male, you refer to BIKINI you get, "There's no bikini here." Following this with a reference to IT produces, "There's no brass loincloth here.", although that's not true. This works similarly with genders reversed.
22. In all versions, if you knock on the south cell door, then Trent/Tiffany yells at you in "a muffled voice". This happens whether the door is open or closed, and no matter where either of you is.
23. In all versions, at Fork, Of Sorts, you can PUSH TRENT INTO HOLE, producing "Trent grabs wildly at you, pulling both of you into the hole." even if you're already in the hole.
