THURSDAY, JULY 31

Outdoor Film: “The Muppet Movie” 
Stretch out on a blanket outside the Library of Congress for this 1979 adventure story, featuring Kermit the Frog, Miss Piggy, Steve Martin, Richard Pryor, and a noteworthy roster of disco-era stars. Get there early and BYO zero-proof drinks and food, though themed bites and bevvies are also available for purchase. (Library of Congress; 8-10 p.m.; FREE) 

One-Day Choir: “Landslide”
Ever wanted to take your rendition of Fleetwood Mac’s beloved ballad out of the shower and into public? Here’s your chance.

Uncle Jesse at The Yards Park
If you’re currently crushing on baby-doll tees, low-rise jeans, and velour, you’ll be right at home at this outdoor concert. Pick up dinner nearby and welcome the weekend as this Y2K cover band delivers tunes from The Backstreet Boys, Outkast, and Shania. (The Yards Park; 7-9 p.m.; FREE) 

Summer Mending Swap
Let’s face it: That torn maxi dress isn’t going to fix itself. Bring it—and any other sad clothing in need of repair—to this mending workshop and get a free tutorial on how to level-up your used duds.

Shark Bites and Brews
Mechanical bulls are so 20th century. Hop on a robotic shark at The Wharf, or laugh along while other brave souls give it a spin. The shark-themed activities don’t end there, though. Sink your teeth into an aquatic-themed donut-eating contest and play outdoor games like “pin the fin on the shark” while listening to rock covers from the 7 Deadlies band. Dogs welcome. (The Wharf; 5-8 p.m.; FREE)
