One thing that got me thinking the other day, is that English is the only language that i know of that has the X-word replacement for swear words. In other languages people either use a similar sounding word (fuck/fudge) or just don't use it. I'd be interested to know why is this and if other languages have a similar way of putting the word in your head without saying it.
