2. It's actually the second-oldest Thanksgiving parade
Okay, TIED with Detroit for second-oldest. Philadelphia lays claim to the oldest, marking the first (/last) time Philly beat New York in anything. Bonus fact: the Santa Claus float at the end of the Thanksgiving parade was also minted in Philadelphia.
3. Those floats are really upside-down marionettes
After designing a store window for Macy's, street performing marionette-ist Anthony Sarg teamed up with Goodyear to create the larger-than-life balloons the parade is known for today, starting with Felix the Cat in 1927.
4. Marionettes that occasionally catch fire. And attack cops.
Poor Felix. The year he debuted in the Thanksgiving parade, he bumped his head on some telephone lines and caught fire. He's not alone, though, in balloon catastrophe: in 1993, Sonic the Hedgehog crashed into and injured an off-duty police officer.
