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 Rollo while you're waiting?" He does wonderful
tricks. He rolls over, shakes hands, 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 balcony railing to the ground 40 floors down.
Just then Paul's date walked out. 

"Isn't Rollo the cutest, happiest dog you've ever seen?" 
"To tell the the truth, " he replied, "he seemed a little
depressed to me."
