My now 7 year old daughter, when she was five, we had a small fire in the backyard, making smores and just hanging out.
D: Dad it would be great if a bird just flew into the fire
Me: What??!!??
D: Yeah, because I want popcorn
Me: WHAT??!!??
D: Well you know, if you cook corn, it becomes popcorn, and birds eat corn, so if a bird flies into the fire, the corn in its stomach will pop and we can have popcorn.
Me:.....
D: DUH Dad
Me:...
D:Why don't birds fly in the fire for us?
I get up and make some popcorn at this stage
Another incident with her
Grandpa after explaining something to her: And do you know why I know this?
D: Because you are really old
