Aggregation No. 1“Matt & Ben” from 10 to 11 p.m. Friday at the Davis Square Theatre, 255 Elm St., Somerville. Tickets are $20.

The play that Cambridge’s Mindy Kaling co-wrote (with Brenda Withers) about Cambridge’s Matt Damon and Ben Affleck, propelling her to “The Office” and onward to stardom, moves to local stages this weekend after a run in Jamaica Plain. (Saturday’s show is sold out already.) In this short play, Matt and Ben, played by Somervillian Lauren Robinson and Libby Schap, spend a long day fighting, reminiscing and hallucinating on the way to writing the Oscar-winning screenplay for “Good Will Hunting.” Information is here.

040816i-Joana-Hadjithomas-and-Khalil-Joreige--I-Must-First-Apologize-…-

Aggregation No. 2Slow Art Day from noon to 1 p.m. Saturday at the List Visual Arts Center, 20 Ames St. Free with registration.

This local celebration of a global event lets art appreciators slow that appreciation way, way down – to five works of art in an hour from the 15 to 30 seconds the average museum visitor spends. The works to luxuriate in with guide Courtney Klemens come from the exhibition “Joana Hadjithomas and Khalil Joreige: I Must First Apologize …” about the cons and fraud discovered in spam email. Afterward there’s a chance for lunch and discussion of revelations at Clover Kendall Square (unlike the visit to the gallery, participants pay for their own lunch). Information is here.

040816i-Jason-toddlers-dancing

Aggregation No. 4Union Square Outdoor Dance Party from 3 to 5 p.m. Saturday in Union Square Plaza, 90 Union Square, Somerville. Free.

After a winter of indoor dance parties to get parents and toddlers out of the house and burning off energy, Kids Union and Arts Union are calling it: It’s time to get outdoors to Union Square plaza. The day is forecast to be dry, if partly cloudy, and hit a high of 50 degrees – so a parka may be called for, but the dancing will keep everyone warm. “The photo opportunities created by hundreds of dancing toddlers in Union Square plaza will be worth it by themselves,” organizers say – and the Lovely Booth photographer will be around for portraits. Make sure to grab one of Gracie’s Ice Cream’s Fruity Pebble marshmallow treat and vanilla ice cream sandwiches. Information is here.
