Words I mispronounce

I have a number of those deliberate ones myself. The long street in Phoenix that was once Business Route I-10 is McDowell, which I pronounce "M. C. Do-well"; I tell people it's the name of a Mountie rapper. Also, a certain family restaurant chain, called by its owners "Country Kitchen", will forevermore be known in my family as "Crunchy Kitten".

The other night on the latest episode of "Diners, Drive-Ins and Dives", a chef announced that he was adding "washed-your-sister sauce" to a recipe.

Whoopi Goldberg always made me chuckle when (on The View) she'd refer to Ahmadinejad as "I'm a dinner jacket."

Myself: I often call Tucson (AZ) "tuck-sun." I think when I first heard of the city it may have helped me remember how to spell it. But I still find myself saying it that way even after living in AZ for 30 years.

EDIT: Just realized I did this with another word (intentionally). When I was teaching science, I'd pronounce "thermometer" as "ther' moh meter" just to reinforce the fact that the device was, like so many other measuring tools, a meter for some physical quantity.

How did you manage to fergit "cow orker"?  As one of my chums at woik used to say, "Well, back to work everybody.  Those cows won't ork themselves!"

The joint campus of Indiana University in Fort Wayne is called IPFW, but one in Indianapolis is IUPUI, pronounced "Ooey Pooey".

I like cow-orker, just haven't remembered all of my mispronunciations yet. First encountered it in Scott Adams' newsletter.

A favorite is the Two Ronnies sketch:
