Background: De Benneville "Bert" Bell (February 25, 1895 - October 11, 1959) was the National Football League (NFL) commissioner from 1945 until his death in 1959. As commissioner, he introduced competitive parity into the NFL to improve the league's commercial viability and promote its popularity, and he helped make the NFL the most financially sound sports enterprise and preeminent sports attraction in the United States (US). He was posthumously inducted into the charter class of the Pro Football Hall of Fame. Bell played football at the University of Pennsylvania, where as quarterback, he led his team to an appearance in the 1917 Rose Bowl.
Context: By early 1933, Bell's opinion on the NFL had changed, and he wanted to become an owner of a team based in Philadelphia. After being advised by the NFL that a prerequisite to a franchise being rendered in Philadelphia was that the Pennsylvania Blue Laws would have to be mollified, he was the force majeure in lobbying to getting the laws deprecated. He borrowed funds from Frances Upton, partnered with Wray, and he procured the rights to a franchise in Philadelphia which he christened as the Philadelphia Eagles. After the inaugural 1933 Philadelphia Eagles season, Bell married Upton at St. Madeleine Sophie Roman Catholic Church in Philadelphia. Days later, his suggestion to bestow the winner of the NFL championship game with the Ed Thorp Memorial Trophy was affirmed. In 1934, the Eagles finished with a 4-7 record, The Eagles' inability to seriously challenge other teams made it difficult to sell tickets, and his failure to sign a talented college prospect led him to adduce that the only way to bring stability to the league was to institute a draft to ensure the weakest teams had an advantage in signing the preeminent players. In 1935, his proposal for a draft was accepted, and in February 1936, the first draft kicked off, at which he acted as Master of Ceremonies. Later that month, his first child, Bert Jr., was born. In the Eagles' first three years, the partners exhausted $85,000 (presently, $1,499,017), and at a public auction, Bell became sole owner of the Eagles with a bid of $4,500 (presently, $79,360). Austerity measures forced him to supplant Wray as head coach of the Eagles, wherein Bell led the Eagles to a 1-11 finish, their worst record ever. In December, an application for a franchise in Los Angeles was obstructed by Bell and Pittsburgh Steelers owner Rooney as they deemed it too far of a distance to travel for games. During the Eagles' 2-8-1 1937 season, his second child, John "Upton", was born. In the Eagles' first profitable season, 1938, they posted a 5-6 record. The Eagles finished 1-9-1 in 1939 and 1-10 in 1940.
Question: Did Bell play on the Eagles?
Answer: he procured the rights to a franchise in Philadelphia which he christened as the Philadelphia Eagles.

Background: Terence Kemp McKenna (November 16, 1946 - April 3, 2000) was an American ethnobotanist, mystic, psychonaut, lecturer, author, and an advocate for the responsible use of naturally occurring psychedelic plants. He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, environmentalism, and the theoretical origins of human consciousness. He was called the "Timothy Leary of the '90s", "one of the leading authorities on the ontological foundations of shamanism", and the "intellectual voice of rave culture". McKenna formulated a concept about the nature of time based on fractal patterns he claimed to have discovered in the I Ching, which he called novelty theory, proposing this predicted the end of time in the year 2012.
Context: In the early 1980s, McKenna began to speak publicly on the topic of psychedelic drugs, becoming one of the pioneers of the psychedelic movement. His main focus was on the plant-based psychedelics such as psilocybin mushrooms (which were the catalyst for his career), ayahuasca, cannabis, and the plant derivative DMT. He conducted lecture tours and workshops promoting natural psychedelics as a way to explore universal mysteries, stimulate the imagination, and re-establish a harmonious relationship with nature. Though associated with the New Age and Human Potential Movements, McKenna himself had little patience for New Age sensibilities. He repeatedly stressed the importance and primacy of the "felt presence of direct experience", as opposed to dogma. In addition to psychedelic drugs, McKenna spoke on a wide array of subjects including; shamanism; metaphysics; alchemy; language; culture; self-empowerment; environmentalism, techno-paganism; artificial intelligence; evolution; extraterrestrials; science and scientism; the Web; virtual reality (which he saw as a way to artistically communicate the experience of psychedelics); and aesthetic theory, specifically about art/visual experience as information representing the significance of hallucinatory visions experienced under the influence of psychedelics. McKenna soon became a fixture of popular counterculture with Timothy Leary once introducing him as "one of the five or six most important people on the planet" and with comedian Bill Hicks' referencing him in his stand-up act and building an entire routine around his ideas. McKenna also became a popular personality in the psychedelic rave/dance scene of the early 1990s, with frequent spoken word performances at raves and contributions to psychedelic and goa trance albums by The Shamen, Spacetime Continuum, Alien Project, Capsula, Entheogenic, Zuvuya, Shpongle, and Shakti Twins. In 1994 he appeared as a speaker at the Starwood Festival, documented in the book Tripping by Charles Hayes. McKenna published several books in the early-to-mid-1990s including: The Archaic Revival; Food of the Gods; and True Hallucinations. Hundreds of hours of McKenna's public lectures were recorded either professionally or bootlegged and have been produced on cassette tape, CD and MP3. Segments of his talks have gone on to be sampled by many musicians and DJ's. McKenna was a colleague and close friend of chaos mathematician Ralph Abraham, and author and biologist Rupert Sheldrake. He conducted several public and many private debates with them from 1982 until his death. These debates were known as trialogues and some of the discussions were later published in the books: Trialogues at the Edge of the West and The Evolutionary Mind.
