CHICAGO — If anyone knows the power of laughter, it’s those of us that work on WGN Morning News!

We’ve had a number of occasions where we’ve not been afraid to show how funny we think something is, especially during the “9@9.” On Tuesday’s edition of the segment, we found out that laughter really is contagious – and there’s research to back it up!

The hosts discussed those while also looking back on some fun laughing moments on WGN Morning News during the “9@9.” We also got the chance to talk about a special anniversary for Michael Jordan, the fate of A.M. radio, the history of sushi in America, the idea of “unschooling,” and more.

You can watch the entire “9@9” from May 16’s show in the video above.
