Georgetown Hoyas
Georgetown's nickname is The Hoyas, but its mascot is "Jack the Bulldog." Various breeds of dogs have been used by the sports teams as mascots since the early 1900s. Several notable bull terriers like Sergeant Stubby and "Hoya" were used at football games in the 1920s, as was a Great Dane in the 1940s. However, in 1951, the school suspended its football program because of the increasing cost of the game financially and academically, which left the school without an official live mascot.
Hooper (mascot)
Hooper (born March 24, 1996) is the mascot of the National Basketball Association's Detroit Pistons. He generally appears as a horse wearing a Pistons jersey. The symbolism is, that like the Pistons they are named after, the team produces horsepower, hence the equine mascot. Hooper became a part of the Pistons team on November 1, 1996, replacing Sir Slam A Lot, and it did not take very long for him to become the most popular mascot in Pistons' franchise history.
