I Started a Joke.

There was a news story today about some voting that went on somewhere, somehow, to come to a consensus about The Funniest Joke Of All Time. And a fairly funny piece of Tommy Cooper daftness won. Fair enough, but I told it to my kids and while they laughed at the idea of a bus driver calling a baby 'ugly', they barely raised an eyebrow at the punchline.

So, the joke that should have won it, as it's the starting point for nearly all kids, a joke so basic that every kid gets it; the joke which acts as training wheels for junior humour...

Knock Knock.
Who's there?
Doctor.
Doctor Who?
That's right! How did you know?

and a variation...

Knock Knock.
Who's there?
Doctor.
Doctor Who?
No, Doctor Doom, this is the Latverian Embassy, isn't it?

I'll be here all week, folks.
