I recently (well, today) read a script in the critique section, laughed like a twat, then realised I'd completely misunderstood the intention of the joke.
The sketch is by ajp (Young, Black and Sketchy) and is apparently a play on the word 'race'. I missed this point completely. By skimming over a crucial piece of dialogue I arrived at a totally different punchline than the one intended.
This means, without any fear of plagairism, I have come up at a joke all of my own. In fact, a series of recurring jokes.
Has anyone else experienced a similar phenomenon? Is there a name for it?
Why didn't i think of that
