Paul got off the elevator on the 40th floor and nervously knocked on his blind date's door. She opened it and was as beautiful and charming as everyone had said.

"I'll be ready in a few minutes," she said. "Why don't you play with my dog Rollo while you are waiting? He does wonderful tricks. He rolls over, shakes hands and sits up, and if you make a hoop with your arms, he'll jump through."

The dog followed Paul onto the balcony and started rolling over. Paul made a hoop with his arms and Rollo jumped through and over the rail of the balcony. Just then, Paul's date walked out.

"Isn't Rollo the cutest, happiest dog you've ever seen?" she gushed.

Paul panicked. "To tell the truth," he said, "he seemed a little depressed to me."
