It’s time to dust off your grass skirt and coconut bra.
They need more than 1,378 people to meet at Welles Park (2333 W. Sunnyside Ave) at 2:30 p.m. to strum along to a traditional Hawaiian song and attempt to break the record.
Don't worry if you don't know how to play -- participants of all ages and all levels will be taught to play a traditional Hawaiian song called "E Huli Ma-kou."
The only catch is that this party is BYOU -- bring your own ukulele.
And you'll definitely need to provide your own grass skirt.
