Doonesbury by Garry Trudeau for June 15, 1973
Zonker: I'm glad you changed your mind, Mike. Mike: I probably shouldn't have. Your mother seemed less than enthusiastic about my coming. Zonker: Aw, you shouldn't take it so personally, Mike. She's always been that way when I bring home friends. She thinks she's got exclusive rights on me. I can understand it, of course. I get home so rarely I suppose I really should be alone with... my parents... more... and... say, Mike, I wonder if you'd mind spending the first few days in a motel? Mike: Yes.
