The reference to "Hurricane Ditka" comes from a regular skit on "Saturday Night Live" that originally aired in early 1991. In the sketch, Chicago-based superfans discuss Mike Ditka's chances of defeating a hurricane, to which one character replies, "The name of the hurricane is Hurricane Ditka."
The segment with Ditka is called "Bill Swerski's Superfans," and it originally starred Joe Mantegna as Bill Swerski and George Wendt as Swerski's brother, Bob. The skit made fun of Chicago sports fans who love to talk about "Da Bears" and "Da Bulls," the NFL and NBA franchises in the city. Merchandise such as T-shirts and sweatshirts with "Hurricane Ditka" logos can be purchased from various online retailers.
