Two animals met in the forest. One said to the other, "I'm blind what kind of animal are you?" The other replied "I don't know, I'm blind too."
The first animal suggested they take turns feeling and describing each other to try to work out what they were.
First animal: "Let's see now, you have long ears, a fluffy tail, nice fur all over."
Second animal: "Fur, long ears, fluffy tail - why, I'm a rabbit. At last I know what I am. Now it's your turn. Hmm, you're long, smooth, slippery, and covered in diamond shapes."
First animal: "Smooth, slippery, covered in diamonds? Oh no, I'm a televangelist!"
