The awesome goons over at Something Awful made another round of up weird D&D 1st edition stuff
(NSFW). They're from a book of magical items that serve mostly mundane tasks. Some of them I can see being useful like the monster that is repurposed (unadvisedly so) to sterilize dishes since it's so good at dissolving all organic matter: You could write an adventure where the monster gets out, wreaks havoc, etc etc etc.
This invention, however, is just weird.
Did they really have to draw the skeleton holding up a bra? Did they? And check out the goofy grin on the skeleton at right.
Other inventions include such anachronisms as ATMs and boom boxes (accomplished via magic instead of electronics). Not sure who would approve this book or decide it belonged in D&D.
