The Phillie Phanatic, mascot of Major League Baseball's Philadelphia Phillies, is an institution, famous for his antics and general inexplicable nature. Born in 1978, the Phanatic is said to be a bird, although he doesn't look like any bird you've ever seen. He's birdlike in that he could be a deranged, many-times-removed cousin of Sesame Street's Big Bird -- which, in fact, he is. But that is the Phanatic's charm, and why the people of Philadelphia, a city with a sense of humor, have embraced him. Like the Muppets' Grover or McDonald's Grimace, the Phanatic is one of a kind and inexplicable -- and Phillies fans love him for it.
