Art of negotiation

Scenario:

Jr takes the basketball hoop from his room into mama's room. Unloads the freshly dried laundry from to-be-sorted-someday laundry basket (the baby's disassembled bassinet, really) and piles it all over the now-knocked down hoop, which has been relabled as "Cranky the Crane" (Thomas fans?)

Proceeds to reposition my footstool adjacent to Cranky and tries to jump onto the pile of Cranky with the clothes. Naani intercepts the jump and the conversation goes like this:

She says to him, "please don't jump, you might get hurt."
"nooooooooo, i hafta jump on Cranky"
"But then you might hurt your teeth if you jump"
"then I will get new teeth" (someone has been learning some dentistry behind my back)
"OK, but first blood will come"
Junior exits the scenario, not enticed any further....
