I've always liked Knock-knock jokes, Doctor, Doctor jokes, Mummy, Mummy jokes - basic humour - and absurd humour too. They're the shortest of stories.
Absurd jokes like:
Q: Why did the plane crash?A: Because the pilot was a loaf of bread.
Was told one the other day that blended two together, and it cacked me up. Ho-hum, so easily amused.
X: Why did Sally fall off the swing?Y: Because she had no arms.X: Knock-knock.Y: Who's there?X: Not Sally.
Oh, and while I'm at it, you should have a look at www.conjunctivitis.com - it's a site for sore eyes.
