Not quite what the OP was asking, but it seems like a good a place as any... Regarding "interesting" improvisational stuff...
I got back to my house from wherever we were with a girl I used to pass some time with... Both of us pretty much had multiple bedroom personalities... never the same game twice... As such, there was usually a Summit of sorts as things were about to go full-tilt horizontal. So on this particular night she says rather suddenly "Oh... Hang on a sec - I want to put something else on." Reaches down, grabs her purse and dumps all her crap out on my bed. After a quick rummage, she finds what she's looking for, rolls back over and shows me with a evil little giggle....

I said "So is that a necklace or a belt?"
It was a belt.
