Funny cat-stories would be fun!

Like:

A dog, a human and a cat were talking and bragging about how scary they were. The dog said:

My jams are so strong that I can bite through any kind of bone!

The human replied:
Somewhat impressive, but humans can make wars that kill billions and destroy the earth!

The cat made a break from his nap, and said:
I just have to scratch some furniture, and then some humans will go mad and kill billions and destroy the earth.
And then he turned around and continue to sleep.
