Oh, well, the Jack O'Neill, IIRC, came with interchangeable hands? I think so he could hold different things? But they never stayed in very well. IDK if I took them off and put them safely wherever his ZAT ended up or if they just fell out and will turn up farther down in the bag, though.

Dejah Thoris was very poorly designed. Her neck had a joint such that you should be able to rotate her head. Except her hair came down far enough that when you tried, it hit her shoulders and popped her head off. I think her head came off about two hours after I bought her. I still have it around somewhere, just never decided what would be the best way to fasten it back on.

(I mean, the real answer is "they go in the Bag of Stuff, like everything else I own that is not a) clothing, b) art supplies, or c) a book.")
