I take it you were providing an example of a slip of the tongue rather than trying to explain how the process works to create one (which is what my question was asking for)?

However, looking at your example you can see that David Coleman (a great exponent of the art of tongue slipping) did actually have the words in his head to say. It was just a matter of them coming out wrong. So if slip of the tongue means saying the words one has in their mind but muddling them up in the execution, then it doesn't help the case of the Weatherman does it?
Are you suggesting maybe that what he actually meant to say was "Coon Martin Luther King Jr. Day"?. In which case what came out was definitely a slip of the tongue.
