The Guinness World Records people officially certify the newest record set by Gilda’s LaughFest in Grand Rapids. Back in March, organizers got 1,675 people to wear sunglasses in the dark.

That goes in the book, along with the three other Guinness World Records LaughFest has set in previous years: the number of people wearing false mustaches, the number of people wearing fake animal noses, and the number of rubber chickens tossed in a single event.

LaughFest is a ten day long comedy festival which, this year, was held in Grand Rapids, Lowell, and Holland with headliners including Jay Leno, Jim Gaffigan, Lily Tomlin, Sinbad, Mike Birbiglia, and Chris Tucker.

Proceeds from the festival will go to support the free cancer, grief, and emotional health programs offered through Gilda’s Club Grand Rapids
