ANOTHER THING I DON'T WANT TO HEAR COME FROM YOUR MOUTH
From Mason's Ghey Tales from the Chocolate Starfish:

Hey.....have you all heard of these guys? The Mischievious Boys??
(Pronounced as "mis-chee-vee-uhs" with four syllables)

Dear Reader, if I ever see you misspell the word 'mischievous,' and subsequently pronounce it 'mischievious,' I will cut out your tongue.

I'm serious about this. Every time I hear someone say 'mischievious,' it sends my into a blind, homicidal rage. And I hear it far too often; once would be enough, but 'mischievous' doesn't seem to be a word some people can wrap their heads around. So now you've been warned: stop it.

Same thing with the 't' in often. But you already know that.
