In Grand rapids, more than 300 people struck a pose, all in the name of laughter.

Participants performed a mannequin challenge outdoors at Rosa Parks Circle in Grand Rapids to celebrate the start of Gilda’s LaughFest 2017, a 10-day festival of comedy to raise money for families dealing with cancer. It’s named for late comedian and Saturday Night Live actress Gilda Radner.

The participants held their pose for nearly four minutes while a video crew recorded it.

LaughFest 2017 featured more than 100 performers in Grand Rapids, Lowell and Holland, Michigan.

This major 10-day Midwest festival was created by Gilda’s Club Grand Rapids and launched in March 2011 to celebrate laughter for the health of it, and support their programs.
