VIDEO: Orangutan bursts into laughter after zoo visitor performs trick

BARCELONA -- This orangutan has a great sense of humor that a visitor to the Barcelona Zoo decided to entertain him with a magic trick.

Dan Zaleski, of Meriden, Connecticut, put a stemmed piece of fruit into a cup and made it disappear. The orangutan watched closely through a glass wall and then collapsed in laughter.

The animal was surprised by the magic trick and seemed to want to see it all over again, just for the fun of it!
