A Hamburger Tree

This evening I asked Dave to watch Miss P while I prepped dinner and this is what happened...

Husband: "Miss P, do you want to go pick strawberries from the garden?
Miss P: "Yes!"
Husband: "Okay, hold on, daddy has to go get his shoes.." [and in a whisper] "and get some strawberries from the refrigerator."
Me: "What's going on?"
Husband: "Miss P won't eat regular strawberries anymore unless she picks them from the garden, so I take the strawberries from the fridge, plant them in the garden and then she eats the shit out of them!"
Me: "Really?"
Husband: " Yeah, she has been doing this for days."
Me: " Maybe we should plant other stuff in the garden so she will eat that too."
Husband: "Yeah, like a hamburger tree."
