Multi-purpose pup

Andrew has an idea in the ongoing battle of Mommy vs. the DOT, over a large tree they want to take.
"We could," Andrew said gravely, "have Murphy poop all around the tree so much that the workers would step in it and run away going 'P-yoo'!"
You know, it might work better than his other idea, which was that his imaginary baby dinosaurs would take coconuts from our (imaginary) coconut tree and throw them at the crew.
