Twin Speak: The Shedd Aquarium in Chicago came up with a program to demonstrate how training porpoises is based upon the same principles as training dogs. They did this to attract visitors while the dolphin exhibit was closed for renovation. The dog act might stay around because it is so popular. Who knew? Well, maybe Barbara (in the red dress) and Lola (pictured above in glasses). And yes, those are real fish swimming around over Lola's head.
