KNOCK KNOCK...IT'S ME...( The top 8 Knock Knock jokes bluetoothed from my brains)

Knock Knock It's Me is a show the critics are calling "utterly formulaic" which is great because it's good to stick to a trusted framework that works.
I haven't fully worked this show out, but I figured when the Edinburgh Festival hits, I could travel up there knock on random doors and deliver these jokes guerilla style. Alternatively if you want to buy the rights to do it yourself and almost certainly guarantee winning the now Defunct Perrier Prize you can for just £1000...
