GRAND RAPIDS, Mich. (AP) -- If it's March, it must be time to try to set another arcane world record in Grand Rapids.
Gilda's LaughFest organizers in the past three years have overseen record-setting attempts for donning false mustaches, wearing chicken beaks and tossing rubber chickens.
The fourth annual festival of laughter kicks off Thursday with an effort to set a new world record for the most people wearing sunglasses at night. Participants are to be given official bright yellow LaughFest sunglasses.
Guinness World Records says the current mark was set in July 2012 by 1,642 people at Chicago's Wrigley Field.
Gilda's LaughFest will run through March 16. It honors the memory of comedian Gilda Radner, who died of ovarian cancer in 1989.
