Many studies suggest that dolphins are the second smartest living organisms behind humans. After all, their brain-to-body proportion is slightly less than a human's. In addition to being known for their innovativeness and their superior ability to teach one another things, dolphins are also notorious for having a good time. 

A video recently surfaced online of a group of dolphins getting high together by capturing a puffer fish and biting into it, subsequently releasing a toxin that induced a state of euphoria. Once they were done with the puffer fish, they simply let it go and enjoyed their "trip" together.
