Having a pool filled with alcohol. Many, many people wish they could have a pool full of alcohol, it's even mentioned in a popular party-ish song. But, there was a man who hand gotten very dirty somehow, I forgot the details, but it's on 1000 ways to die, decided hed take a bath with rubbing alcohol. Well he filled his tib with it, and got in, he scrubbed and scrubbed, he soon passed out and died of acute alcohol poisoning. Our skin absorbs alcohol through the skin, and, well, it'll kill you.

That story was based on a woman who Submerged herself in a tub full of alcohol during the SARS epidemic. It's on the 'list of unusual deaths' on Wikipedia.
