During Emanuel's appearance Tuesday on NBC's "Tonight Show," Fallon agreed to bring his production to Chicago for a few shows if Chicago Public School students read 2.4 million books this summer. That would mean the school system's more than 400,000 students would have to read six books each.
Emanuel's appearance with Fallon was the result of a previous deal between the two men. The mayor agreed to appear on the show if Fallon participated in Chicago's Polar Plunge into Lake Michigan in February.
Fallon took part in the event dressed in a business suit.
