The cat

A man had a cat that howled all night, every night. The sleepless man concluded that the cat had too much testosterone and took him to the vet to be "fixed." 

To the great surprise of the man and all his neighbors, the cat continued howling.


"Why are you doing it now?" they asked the cat.


"Now, I am a consultant," responded the cat.


Moral of the Story: Those who have something of their own to work with, do so. Those who don't have their own, become consultants.
