Union Hall will smell like teen spirit tonight for the ’90s Alternative Sing-Along — a karaoke night where everyone sings and dances to every song. Come in your best flannel — or maybe dressed like that weird bee girl from that Blind Melon video — and you could win ’90s-themed prizes. Even if the decade is a blur of smoke and Zima, you can still sing the chorus to “Mmm Mmm Mmm Mmm” by the Crash Test Dummies.
9:30 pm at Union Hall [702 Union St. between Fifth and Sixth avenues in Park Slope, (718) 638–4400, www.union

The Super Ridge 5K Run invites you to dress up like your favorite superhero or super villain and run or walk about three miles through Shore Park.

10 am at Narrows Botanical Garden [7200-7398 Shore Rd. at Mackay Place, www.super
