Fun With Words

So I walked into my local fish shop to pick up some mussels for our dinner. The word for mussels in Italian is cozze. Since working in the pub I've really started to pick up all of the swear words that I love so much in English. The more vocabulary I have the better, right? The "F" word in Italian is cazzo. In my head I had everything worked out in terms of how many grams of mussels I needed and even how to say it correctly. So I step up to make my order and say "Vorrei (I would like) cazzo." very calmy and very well (so I thought). Now, look at the word for mussels and the "F" word. Pretty close, right? Switch some vowel sounds around and there you go. Some how I had switched the two words in my head and uttered a sentence fit only for sailors. So the guy behind the counter says to me in English, "I don't think you do." Face goes bright red. As I realized what I had just asked for I turned and broke the hell out of the place never to be seen again.
