He calls his wife over to his side and says, "When I pass I want you marry farmer Jones down the road."
"I could never do that. I just couldn't ever marry anyone else," Mrs. Brown responded.
"I insist," said farmer Brown.
"I couldn't," Mrs. Brown shot back.
Farmer Brown explained, "But his wife passed long ago and he needs a help-mate around his place. It's the right thing to do."
"I said I couldn't," said Mr's Brown, "and I can't believe you're inisiting on this. Why are you being so adamant about me marrying farmer Jones?"
Farmer Brown pulled her close to him and whispered, "He cheated me in horse deal one time."
