why did no one tell me about "minced oaths"?

almost an entire lent's worth of censoring my profane exclamations, and i only just now find out there's a word for that! 

a "minced oath" is a polite substitution for a profane or blasphemous expression. well golly gee willikers, that covers all the bases of what i gave up for lent! (googling golly willikers to find out how to spell it for my last post is how i stumbled upon the phrase "minced oath" in the first place.)

examples include things like: "oh my goodness" instead of "oh my ***," and "darn" instead of "****," and so on.  

anybody have a personal favorite minced oath?

edit: my favorite so far is my fiancé saying "fecal demonstration" in place of "sh** show."
