It may seem that most sitcoms, comedians and improv schools are in New York....but a new survey says you'll find more laughs somewhere else. ABC News reports it may be the 'Second City,' but Chicago's first on this list. The Windy City tops the latest rankings by the University of Colorado's Humor Lab.....no joke...of the nation's funniest cities. It's based on an algorithm that takes everything from tweets to the number of comedy clubs per square mile into account. Jack Benny called it home....so Redd Foxx, Bonnie Hunt....brothers John and Jim Belushi and Bill Murray. Even sports are funny! (da bears!) Boston was second.....the home of Seinfeld and Saturday Night Live, New York...was sixth.....followed by...Los Angeles.
