Instance of flawless, linear logic by a child that can not be beaten!!!! One of the earliest ones on record: Boy aged 4: Dad, I’ve decided to get married. Dad: Wonderful; do you have a girl in mind?! Boy: Yes... grandma! She said she loves me, I love her, too....and she’s the best cook & story teller in the whole world!! Dad: That’s nice, but we have a small problem there!! Boy: What problem?! Dad: She happens to be my mother. How can you marry my mother!! Boy: Why not?! You married mine!!!! jayasala42
