another pun..

One day Roy had to teake an overnight train to another city. Since this was a new venture for him, he had purchased a new wardrobe. Arriving on the train, the conductor informed Roy the proceedures. He mentioned that if he wanted his shoes shined, to leave them out his door at night and they'd be ready in the morning.
At sunrise, Roy heard a commotion out his door. Upon investigating, he say a cat gnawing at his new loafers. The cat scat. With the help of the conductor and others aboard the train, they finally found the feline where they all broke out in song:

"Pardon me Roy, is this the cat that chewed your new shoes?"?
