Making plans? Short on ideas? No worries. See Milva DiDomizio and Courtney Hollands's picks for the top things to do around the Hub this weekend. Take a peek, then get out:
Jon Lovitz: As a young man, Lovitz hoped to become an actor, but he was a little too funny to play the serious guy. In the 1980s he turned to comedy, landed a job on Saturday Night Live, and has been making people laugh ever since with his distinctive voice and many characters (Tommy Flanagan of Pathological Liars Anonymous, Master Thespian, and Hanukkah Harry among them). He has also managed to make it into several movies (more than 30, actually) as well as pick up an Emmy nomination, appear on Broadway, sing at Carnegie Hall, and open his own LA comedy club. Friday, he's in funny old Boston. 7:30 and 10 p.m. $25, $29. Wilbur Theatre, 246 Tremont St., Boston. 800-745-3000, thewilbur.com
Gondoliers Prom: Somerville bands the Gondoliers and the Secret Sea will play metal, electro rock, and punk, and the Big Digits DJs will spin mashups and hip-hop (they sample Joan Osborne, y'all) at this annual party. Cheesy prom attire — think powder blue tuxes and puffy sleeves — is welcome. We aren't holding our breath to hear our prom song: Edwin McCain's "These Are the Moments." Barf. 21+. 8:30 p.m. $10. P.A.'s Lounge, 345 Somerville Ave., Somerville. 617-776-1557. paslounge.com
Unhappy Birthday: You'd go out tonight, but haven't got a stitch to wear? Well, just throw something on and fete Morrissey Saturday (his actual birthday) at Great Scott with a gaggle of local bands and musicians — including the Honors, Ad Frank, and Jay Marsh — and DJs Michael V and David Virr. Expect Morrissey and Smiths covers all night long. 21+. 9 p.m. May 22. $7. Great Scott, 1222 Commonwealth Ave., Allston. 617-566-9014. greatscottboston.com
Spring Festival and Perennial Divide: Gardeners, it's time to gather samples of your best plants and bring them to the Boston Natural Areas Network event. Bring some containers, too, for collecting choice specimens from fellow backyard growers. If you're a beginner and don't have anything to offer, don't worry. There are plenty of plant divisions to go around. The event also features native plants and vegetable seedlings from local farms, a beekeeping workshop at noon, self-guided tours of the Learning Garden, and networking opportunities. 10 a.m.-2 p.m. Free. Rain or shine. City Natives, 30 Edgewater Dr., Mattapan. 617-542-7696, bostonnatural.org
Radio 92.9 EarthFest: If you're one of the more than 100,000 people expected at this show, be ready to participate in the comprehensive recycling program. You can also take advantage of renewable energy certificates from First Wind, and consider using the International Bike Center's free bike-valet program instead of driving. The festival is all about helping the environment, after all — even if you're going mostly for the music lineup, which includes Collective Soul, the Gin Blossoms, Crash Kings, and Marcy Playground. There's also the interactive Kids' Planet, local environmental organizations, and displays. 11 a.m.-5 p.m. Free. DCR Hatch Memorial Shell, Storrow Dr., Boston. www.earthfest.com
Crooked Still: Being snowbound in a recording studio in Virginia turned out to be serendipitous for these young contemporary folikes. The result is the band's fourth studio album, "Some Strange Country." Vocalist Aoife O'Donovan, banjoist Gregory Liszt (who's toured with Bruce Springsteen), bassist Corey DiMario, cellist Tristan Clarridge, and fiddler Brittany Haas come home to Boston for the CD release. The new record adds originals and a cover of the Rolling Stones' "You Got the Silver" to the ensemble's innovative arrangements of traditional tunes. 18-year-old bluegrass wunderkind Sarah Jarosz opens. 8 p.m. $22, $28. Sanders Theatre, 45 Quincy St., Cambridge. 617-876-4275, worldmusic.org
SATURDAY & SUNDAY
Boston Theater Marathon: How long does it take to present 50 10-minute plays by 51 playwrights produced by 50 theaters? At the Boston Theater Marathon, just 10 hours. The annual event encourages collaboration between artists and producers, and often serves as a catalyst for later full-length productions. Saturday's warm-up laps feature works by Martha Jane Kaufman, Richard Snee, and Lydia Diamond. At Sunday's big event, look for pieces by Israel Horovitz, Robert Brustein, Katherine Snodgrass, and Melinda Lopez. Warm-ups: 1, 4, and 7 p.m. Saturday. Free; Marathon: Noon-10 p.m. Sunday. $30, $25 advance. Boston Center for the Arts, Calderwood Pavilion, 527 Tremont St., Boston. 617-933-8600, bostontheatrescene.com
'Mariko Kusumoto: Unfolding Stories': Polishing the fancy metal ornaments in the 400-year-old Buddhist temple where her father served was one of sculptor Mariko Kusumoto's childhood chores. The ornaments' gleam left a lasting impression on her imagination. Today, she uses various metalsmithing techniques to create music boxes, clocks, and other types of metal sculptures. The Fuller Craft Museum presents her work, known for its intricacy and meticulous detail. 10 a.m.-5 p.m. both days ( through August 8). $8, $5 seniors and students, ages 12 and under free. Fuller Craft Museum, 455 Oak St., Brockton. 508-588-6000, fullercraft.org
They Might Be Giants family show: John Linnell and John Flansburgh met when they were teens growing up in the Boston suburb of Lincoln. Together they founded Grammy Award-winning alternative rock band They Might Be Giants. Their 2009 release "Here Comes Science" is a CD/DVD that aims to educate and entertain with songs like "Meet the Elements," "I Am a Paleontologist," and "My Brother the Ape." A pair of weekend family concerts benefits Boston By Foot. Noon and 3 p.m. $22. Regent Theatre, 7 Medford St., Arlington. 781-646-4849, regenttheatre.com
Blue Hills Mountain Bike Day: Grab your two-wheeler (don't forget the helmet) and kick off the summer season with the DCR Rangers, Blue Hills TrailWatch, and the New England Mountain Bike Association. Guided rides for all levels, contests, an obstacle course, and a limbo competition are planned. 10 a.m.-2 p.m. Free.
