Pneumonoultramicroscopicsilicovolcanoniosis.  That is a word.  A real word!  We learned it in language class. We had to break it down into small words we could understand.  The definition of Pneumonoultramicroscopicsilicovolcanoniosis is: a disease you get in your lungs that is caused from breathing in too much ash or volcanic air.  Awesome right?
