How do you get a rat to laugh? Telling a joke won't work, but scientists say a rat will laugh when tickled and they're not joking!
One of the most cited studies on this interesting animal behavior comes fromDr. Jaak Panksepp, professor of veterinary and comparative anatomy at Washington State University in Pullman.
When Dr. Panksepp tickles rats' bellies, the animals appear to laugh, and their giggly behavior suggests that humans aren't the only mammals with emotional lives. Rat "laughter" consists of high-frequency chirps that are beyond the range of human hearing.
