I'm more likely to do it by deliberately mispronouncing the word: "friend" was "fry-end" in my head for years in elementary school, and this one will be jee-oh-PARD-ize until I get it right.

It also helps that I have a strong background in Latin; I'm not likely to get "conscious" wrong so long as I remember it's based on the root verb scire. But that only works on words for which I know the roots.
