Timothy Francis Leary October 22, — May 31, was an American psychologist and writer known for his strong advocacy of psychedelic drugs. He was "a hero of American consciousness", according to Allen Ginsberg , and Tom Robbins called him a "brave neuronaut". The scientific legitimacy and ethics of his research were questioned by other Harvard faculty because he took psychedelics along with research subjects and pressured students to join in. Leary believed that LSD showed potential for therapeutic use in psychiatry. He popularized catchphrases that promoted his philosophy, such as " turn on, tune in, drop out ", " set and setting ", and " think for yourself and question authority ". During the s and s, he was arrested often enough to see the inside of 36 prisons worldwide.

Cow tipping is the purported activity of sneaking up on any unsuspecting or sleeping upright cow and pushing it over for entertainment. The practice of cow tipping is generally considered an urban legend ,  and stories of such feats viewed as tall tales. Cows routinely lie down and can easily regain their footing unless sick or injured. Scientific studies have been conducted to determine if cow tipping is theoretically possible, with varying conclusions. All agree that cows are large animals that are difficult to surprise and will generally resist attempts to be tipped. Estimates suggest a force of between 3, and 4, newtons and pounds-force is needed, and that at least four and possibly as many as fourteen people would be required to achieve this. In real-life situations where cattle have to be laid on the ground, or "cast", such as for branding , hoof care or veterinary treatment, either rope restraints are required or specialized mechanical equipment is used that confines the cow and then tips it over.
