Bob goes to a grocery store and spots cat food at special prices. He picks a dozen cans of cat food and goes to check out. The Manager gets suspicious. Bob doesn't strike him as the cat owning type and thinks he's buying it to feed his kids. So he asks Bob to show him his cat before he will let him have the cat food. So Bob goes home and returns with a cat which forces the reluctant manager to sell him the food. The next week Bob is back at the store and finds dog food on special. He picks out a dozen cans and heads for the check out. Again the Manager is suspicious. He thinks that this guy may have a cat but no way he has a dog and that the dog food is really for his kids. So, he asks Bob to go get the dog and bring it back to show him it really exists before he can let him have the food. So Bob heads for home and soon returns with a dog. The Manager again has to back down and sell him the dog food. Next week Bob comes to the grocery store with a bag. He asks the manager to put his hand in the bag. Somewhat curious the Manager obliges and immediately pulls it back out. He looks at Bob and shouts: "What the f4ck?! This is sh1t!" Bob calmly replies: "Yes! And I want to buy some toilet paper..."
