Whatever you do, DO NOT put it in the microwave. I'm not sure why anyone would try it but a gal that used to work at a store I used to go to did this and when she opened the door the bottle exploded and she lost an eye.
Maybe put it in cold or hot water for 15 min, dry it off and try to open? Maybe dab some polish remover around where the lid screws on....or just get a new bottle! ...you could secretly replace the old bottle w/the new one and your manhood (at least in appearance) would stay intact.
Also, did she try wearing rubber gloves to open it to get a good grip?
