Before I continue with this post I need to give you a STRONG LANGUAGE WARNING! If you don't like swearing move along now.
Many films that want to be true to real life feature swearing in them. Whilst they're on show at the cinema this is OK because they can be rated as age appropriate. But if they are successful films they are going to inevitably make it to TV where there are no such restrictions. This means they are going to have to be censored. They can be "bleeped" of course, but quite often somebody has the bright idea of re-recording the dialog to convey something less controversial. Below are some of the more hilarious attempts.
