In a Reddit "Ask Me Anything," Nick Offerman answered a variety of fan questions pertaining to his portrayal of Ron Swanson on "Parks and Recreation." u/alvinsingle asked what the hardest part of playing Ron Swanson was, to which u/NickOfferman replied, "Keeping a straight face in the onslaught of hilarity from all of our cast, except Jerry." Clearly, the cast can't resist roasting Jerry (Jim O'Heir) even when they're not in character.
Additionally, u/cutiepatootieadipose asked Offerman how hard it was to keep a straight face while playing Ron, because, "The delivery of some of your lines has me laughing so hard. I loved drunk Ron and your tiny hat!" Offerman replied under account handle u/NickOfferman, saying, "It is very hard to keep a straight face because my castmates are literally the funniest collection of people working today. Amy and Pratt and Aubrey and Aziz and Adam and Rob and Rashida and Retta. Every single cast member. Devastatingly funny."
