The next day, he decided to drive the cat 40 blocks away and try the same thing.
As we was driving back into his driveway, there was the cat! He kept taking the cat farther and farther away, but the darn cat would always beat him home.
At last, he decided to drive a few miles away, turn right, then left, past the bridge, then right again and another right and so on until he reached what he thought was a safe distance from his home and he left the cat there.
Hours later, the man calls home to his wife: "Jen, is the cat there?"
