Annual Italian Feast of Saints Cosmas and Damian all weekend long at Warren and Cambridge streets, in the Wellington-Harrington neighborhood. Free.
This 91st annual family-friendly feast includes free performances by recording artists such as Exposé, Martha Wash (“It’s Raining Men”) and The Drifters, and many more, along with rides, games, a food festival (with cooking demonstrations by local chefs), eating contests and parades.

The free Somerville Greek Festival goes all weekend also, at 29 Central St., in the Spring Hill neighborhood of Somerville, with food, live music and dancing. More Armenian than either? There’s also a Trinity Family Festival at noon Sunday at the Holy Trinity Armenian Church of Greater Boston, 145 Brattle St., West Cambridge, with shish kebab, losh kebab, doener kebab and more, kids’ activities and live music. It’s free, but RSVP and buy food tickets here.)

Now in its ninth year, this five-day festival (running since Wednesday) showcases 300 artists doing improv, standup, sketch, music, variety acts and everything in between, even throwing in workshops and networking for the pros who’ve come to learn – or show off.

“TV Guidance Counselor” 250th Episode Saturday Sleepover Spectacular from 7 to 9 p.m. Saturday at Comicazi, 407 Highland Ave., Davis Square, Somerville. Free.
Ken Reid has carved out his own space in the comedy world – crammed into his home among his massive collection of movie, television and comic book memorabilia. That includes the decades’ worth of TV Guide magazine he’s collected, which he pores over with celebrity guests to “explore the tough television-watching decisions of our past.” With the release of his 250th episode (examining the issue of Oct. 3-9, 1981, with actor, voice actor and comedian Larry Murphy of “Bob’s Burgers”), Reid and Murphy will hold a live celebration with trivia, rare television clips and special prizes – including a “TV Guidance Counselor” sleeping bag. Pajamas-wearers welcomed. Information is here.
