I'm 20 years old, by the way...
Up until tonight, I believed that Molotov Cocktails were a kind of drink. I was talking on the phone with my mom, when she told me of this story on the news about a man in New York City who stood on top of a building, and threw Molotov Cocktails off of the building and onto the street, causing really bad damage. I was totally baffled as to why anybody would want to throw a bunch of drinks off a building. I even had this mental image of some guy on top of a tall building, throwing drinks in these little cocktail glasses onto the street. My response to this was, "Wow, sounds like *he* had a few too many Molotov Cocktails!", wondering why in the hell anyone would want to do such a weird thing. It was then that I found out that Molotov Cocktails are actually bombs that start on fire when you throw them at things.... oh dear...
