Two cats are sitting in the back yard of a house.

The lady of the house is standing on the back porch, calling, “Here kitty, kitty, kitty.  Here kitty, kitty. . . ."

The first cat looks at the second cat and ask,
“Isn’t that your human calling you?”

Second cat says, “Yup.”

First cat says, “Aren’t you going to go see what she wants?”

Second cat says, “Why should I?  She’s only called me 87 times.”
