The conversation started out with Max wondering how he'd pick his profession. When I told him he doesn't have to decide until college, he told me that he wanted to marry his Grammy, that would be his job.
"I want to marry Grammy. I want to stay with her and live in her house," Max said.
Good work if you can get it ... 
A day later, younger brother Ben could not let this go.
"Dad, is Grammy married?," Ben asked while the family was on a weekend excursion
"Yes, Grammy is married to Grampy," I said.
"Ha-ha, Max. You can't marry her," Ben said. "She's already married."
"Yes I can," Max screamed. "I asked her and she said OK."
