What is "birdzerk!"

BirdZerk! is the performance name of Dominic Latkovski, a professional mascot and entertainer known for appearances at American minor league baseball games. He is most known for his skits that revolve around pranking players, umpires, bat boys, and managers and his acrobatic, synchronized dances with his sidekicks BirdZerk Jr., BabyZerk!, BallZerk!, and DogZerk!. In 2008, BirdZerk! was named as the top minor league baseball promotional act by CNBC sports business columnist Darren Rovell.
