The couple, Cierra Howard and Kevin Timpson, have made it a ritual during the past six months to read comic strips with each other after dinner, the Sacramento Bee reported.
Howard's favorite comic, "F Minus" had a special message Monday.
"Cierra, will you marry me? -- Kevin," it read.
When Howard looked up from the paper, confused, Timpson was down on one knee, holding a ring.
"I wanted to do it in a way no one I knew had ever proposed," said Timpson. "I wanted to surprise her and make her laugh. She has a really good sense of humor."
Timpson contacted Tony Carrillo, the author of "F-Minus" for help with his proposal.
"No one had ever asked me to do something like this before," Carrillo said.
The strip features a man kneeling on a bench holding a ring out to a woman with a plane toting a banner overhead with the proposal on it.
"I loved how he proposed," Howard said Tuesday. "It's totally him. It's totally us."
