I was one of those inebriated youths. Luckily, when I arrived at the hospital for treatment a kidney had just been delivered that was a perfect match.

I once found a perfect match - perfect in dimension, colour, composition and chemical balance. I kept it mounted in a glass frame above my living room window but it was reclaimed by the bailiffs three years ago, who discovered that it had been crafted in the workshops of Alexander the Great, and it now stands in the Hall of Fame in the Museum of Pyrotechnics in Droitwich.

I once invented a universal solvent, but I couldn't find anything to keep it in.

Last week I successfully patented the sky.

I have patented the lie. You lot owe me a hell of a lot of money. Then I'm off to Parliament...

Well I patented fiction, so you all owe me money

You can walk across quicksand as long as you show no fear. Quicksand can smell fear. Oh, and whistling won't help, it just annoys it.

I patented patenting. Cough up, lads.

I had prior art to defeat Tuj's patent, but someone had already patented the research of prior art and they want me to pay an exorbitant licence fee.
