It's weird how certain people pronounce certain things incorrectly, and as if it's some sort of cosmic joke, these people are doomed to proclaim their mispronunciation skills on a regular basis. 

Such is the case with most people who pronounce nuclear as "nucular".  In my own life, I would say the word nuclear comes up maybe once every few months, perhaps as I drive past a nuclear power plant or am talking about the idea of nuclear nonproliferation treaties (which, oddly enough, isn't often).  But for people who pronounce it "nucular," the topic seems to come up every day.  Perhaps every hour.  I didn't know this recent presidential election had much to do with nuclear anything, but that Sarah Palin must've said "nucular" at least eight times in every one of her speeches. 

Another example is Wendy's mom and her mispronunciation of the dog breed Lhasa Apso as "Opsa Lopso".  Before I started dating Wendy, I had never heard of this type of dog.  I heard Wendy mispronounce it a few times, and then I heard the source.  I alerted Wendy to the mistake, and she passed it on to her mom, but I swear I hear the woman mispronounce this dog type every time I see her.  I don't understand how this topic keeps coming up. #language
