Language mix-up

I'm known for fluffing my lines or saying the wrong thing like Phillip Schofield's old screen wife, but why can't people chill? I've already mixed up with the days, this time my language is the one I should be paying attention to. If I'm not mixing up with people's names, I'm saying stuff I don't usually say such as an 'F' word. I don't say it unless I block half the word out, but do you think I should stop listening to Lily Allen on the ipod and ignore folks's filthy language? Ooops!
