To a generation of comedy lovers, Peter Riegert always will be "Boon" from Animal House. Now Riegert is old enough to be playing Seth Green's father in the rookie sitcom Dads.
Riegert finds it both intriguing and a little frustrating to compare the controversial humour of Dads - which airs Tuesdays on Fox and City - to the comic stylings of Animal House, a film that came out in 1978.
"What's offensive to somebody else is not to me, and what's tame to somebody else is offensive to me," says Riegert, 66. "Once you go out of the house, you run the risk of offending someone. Once you open your mouth, somebody is going to get offended. And in this regard, it's fascinating to hear what offends people.
"Animal House is tame compared to what happens on some shows now. And yet some of the stuff in Animal House, you couldn't get away with today because people would be so offended."
Executive produced by Family Guy's Seth MacFarlane, Dads stars Riegert, Green, Giovanni Ribisi and Martin Mull as two father-son tandems. When the pilot episode was seen by critics last summer, Dads took considerable heat, as many observers found it quite racist and sexist by 2013 broadcast-network standards.
"It's not a movie and it's not a play - it's literally going to be discovered from week to week, 22 minutes a week, based on what they learned in the previous episodes," Riegert says. "Over the course of however long it runs, then you'll have a tapestry of what it is. I don't think you can know that from one episode to the next.
"But we have to speak with conviction, that's all you can do, it's what you're hired for. Whether people think I'm good at it, I have no idea. All I know is, I can't say the lines unless I'm saying them with conviction."
Comedic conviction comes in countless forms these days.
"YouTube can have some of the most grotesque images you could imagine, and if that grotesque image is of an individual who wants to be an actor and they get 3 million hits, they're going to get hired for something that people like me used to get hired for - now that's offensive," says Riegert, prompting laughter.
"But at the end of the day, all I can deal with is my own choices. I was excited that Seth MacFarlane was behind this. I was absolutely thrilled when I got the role. I believed in the material, and I believed the material was going to attract talent.
"That has been my whole experience as an actor. If I can have the luxury to choose, most of the time I've been in really interesting jobs, some of which were provocative."
So in terms of Peter Riegert's career, Animal House was the father of Dads? It's up to you whether you want to have a food fight over that one.
