What circumstances make it okay to live with your parents as an adult? “There’s nothing empirical. If you’re making weird paintings that don’t sell well but get reviewed, and if you’re handy around the house, and your mother is single, stay home. If your parents hate you, if they’re very Republican, you should probably leave.” —MARK DUPLASS

—JASON SEGEL

Is there a cutoff age for when you really have to move out of mom’s basement? “No. There’s no cutoff age. That’s ageist. That’s a bigoted point of view. And people always rag on people in basements. Basements are awesome. That’s where make-out sessions happen. That’s where ping-pong tables are located. Good things happen in basements.” —JUDAH FRIEDLANDER

—PADMA LAKSHMI

How long is it appropriate to live in your parents’ basement once you’re an adult? “I guess it’s based on circumstances. You can live at home and have a productive, healthy life, but if you’re doing it to dodge responsibilities, then maybe they should crack the whip.” —ED HELMS

—JAY PHAROAH

Have you spent time in the family basement? Gone down there to do what Jeff does? “Oh, I’ve done that. At Christmas, I go downstairs to smoke pot.” —JUSTIN KIRK

—KAYLEE DEFER

Were you smoking pot in your mom’s basement when you still lived with her? “No. I wouldn’t smoke weed. I’d go for walks in nature.” —JONATHAN AMES

—BOBBY CANNAVALE

How old were you when you moved out of your mom’s house? “Three, three-and-a-half. But I was a little mature for my age.” —MIKE CAHILL

—MEREDITH OSTROM

Your character didn’t seem like she’d want her kids smoking weed in the basement. Would you have a problem with it? “I don’t mind if they’re smoking weed in the basement if they have a job, and they’re functioning. The problem with smoking weed all the time is if you’re not productive. Some of the most productive people I know are smoking weed. So it’s not necessarily a bad thing.” —SUSAN SARANDON
