Whipped Lightning is ok.  More of a novelty really.  Yes, it is 18% alcohol by volume, however the can's contents are only 375ml I think.  So thats just over a beer can's volume, and figure a beer is 6%ABV... So if you consume the entire can of whipped cream, you get the alcohol effect of around 3 - 4 beers.  Also, at my liquor store it was 9.99$ for a can.  Pretty inefficient, but fun nonetheless.  I made shots of expresso flavored vodka with the vanilla Whipped Lightning on top, pretty tasty combo.
