You almost spelled pneumonoultramicroscopicsilicovolcanoconiosis right, but you didn't. You gave it your best, but you failed to spell it. And you were only one letter off, too.
Your in the national spelling bee, your going against the best person so far. Everyone else is out. Then you get your word.
"Spell pneumonoultramicroscopicsilicovolcanoconiosis."
"Language of origin?"
"I'm sorry that's incorrect. You were SO close, though. Only one letter off."
And then you almost have a mental breakdown, but the opponent also spelled "pneumonoultramicroscopicsilicavolcanoconiosis."

a lung disease caused by silica dust but more probably (in my opinion,) THE LONGEST WORD IN THE WORD! Really, I actually copy pasted that word: pneumonoultramicroscopicsilicavolcanoconiosis from google but anyways I think my keyboard is tired.
