Since you raised the subject of cats, I'd like to share an invention with you. I'll just paste in a copy of the e-mail that I sent to Ellen Degeneres about it last January. (She never responded, so I guess it's not as good as I thought.) Dear Ellen;
Being a fellow cat lover, with a huge audience, you are probably the best person to share this innovation with others.
It is perhaps my greatest, and definitely most annoying, invention to date. I believe it to be the best cat toy in existence. As a gift to humanity, I have decided not to patent it or seek royalties. Anyone can easily make one at home for very little cost. A brief construction guide (the only kind possible) goes as follows:
1) Place golf ball in empty bath tub.
2) Insert cat.
Unfortunately, it sounds like a tyrannosaurus rex farting in a kettle drum. Something quiet like a ping-pong ball would be easily batted out of the tub, which would defeat the purpose of confinement and prevention of loss under the furniture. (Lucy did once manage to get the trajectory and power just right to achieve escape velocity and fire it into the laundry, but she has never repeated it.)
I expect that dipping the ball into liquid latex (available at hobby shops) would quiet things down considerably, with the bonus of adding a random component to the path of the ball due to inconsistent coating.
Please pass this knowledge on to your viewers, as I would like to see my invention installed in every home with a cat.
Oh! Never mind; she just launched it into the toilet. (That was a joke. She didn't really. I just wanted to see if I could get a giggle out of you.)
Cheers;
Dan
